Abstract:
A spectral element method for analyzing wave propagation in multiply connected plates oriented at arbitrary angles is presented. These plate elements may be joined to model structures with stiffeners, open or closed thin-walled tubes, corrugated plates, channels, and ducts. The element models exactly both in-plane and out-of-plane responses over large domains. Results for point impact of a plate with stringers and a thin-walled box beam show excellent agreement with finite element solutions.

Abstract:
An element-free Galerkin method for the solution of free vibration of symmetrically laminated folded plate structures is introduced. Employing the mature meshfree folded plate model proposed by the author, a folded laminated plate is simulated as a composite structure of symmetric laminates that lie in different planes. Based on the first-order shear deformation theory (FSDT) and the moving least-squares (MLS) approximation, the stiffness and mass matrices of the laminates are derived and supposed to obtain the stiffness and mass matrices of the entire folded laminated plate. The equation governing the free vibration behaviors of the folded laminated plate is thus established. Because of the meshfree characteristics of the proposed method, no mesh is involved to determine the stiffness and mass matrices of the laminates. Therefore, the troublesome remeshing can be avoided completely from the study of such problems as the large deformation of folded laminated plates. The calculation of several numerical examples shows that the solutions given by the proposed method are very close to those given by ANSYS, using shell elements, which proves the validity of the proposed method.

Abstract:
The discrete-Kirchhoff Mindlin quadrilateral (DKMQ) element has recently been developed for analysis of composite laminated plates. This paper presents further development of the DKMQ for analysis of composite laminated folded plates. In this development, a local coordinate system is set up for each element at its centroid. The DKMQ stiffness matrix is superimposed with that of the standard four-node plane stress quadrilateral element to obtain a 24-by-24 folded plate stiffness matrix in the local coordinate system. To avoid singularity of the stiffness matrix, a small stiffness coefficient is added in the entries corresponding to the drilling degrees of freedom. The local stiffness matrix and force vector are then transformed to the global ones and assembled. The accuracy and convergence of the folded plate element are assessed using a number of numerical examples. The results show that the element is accurate and converge well to the reference solutions.

Abstract:
The eigenfunctions of a continuous beam are found numerically. The folded plate type of finite strip with intermediate supports is formulated by combining such an eigenfunction in the longitudinal direction with an appropriate finite element shape function in the transverse direction. The numerical examples given in this paper, such as the continuous beam and plate, demonstrate the advantages of this method: simplicity, accuracy, and convenience. Key words: finite strip, continuous structure, eigenfunction, folded plate, plate bending.

Abstract:
Persistence of research was towards the behaviour of folded plate. In this project, we used GGBS blended ferrocement concrete to cover a folded plate 600 mm x 1800 mm x 150 mm. Ferro cement is a building material that is emerging as an alternative for traditional RCC. According to prior research, folded plates are the most cost-effective and visually acceptable option for longer span roofs. First, we built the folded plate model in ANSYS and investigated its behaviour in terms of load versus deflection. Later, for experimental purposes, we cast a folded plate coated with GGBS mixed ferrocement concrete. The results of the experimental inquiry demonstrate that there was an improvement in flexural behaviour when compared to the traditional model. The same was verified using ANSYS findings. ANSYS analysis aids in comparing and summarising experimental data. Both the analytical and experimental inquiry results show that ferro cement structures are a good alternative to RCC since they are less costly and lighter. Because folded plates retain their effectiveness for a longer length of time when Ferro cement is utilised. Ferro cement has made the components smaller to support the load because ferro cement parts are high in stress when reinforcement is spread.

Abstract:
Partitioning of finite strains in different domains within the limb and hinge regions of a fold can be used to understand the deformation processes operative during fold formation. Samples taken from the limb and hinge regions of a gently plunging, asymmetric, tight, mesoscale fold in the Erwin formation of the Blue Ridge in North Carolina were analyzed to determine the deformation mechanisms and strains associated with the folding event. Rf/phi grain shape fabric analysis was conducted for each sample and used to calculate the orientation and magnitude of the final grain shape fabric ellipsoids. Flexural folding and passive-shear folding models predict that the highest finite strains will be recorded in the hinge of a fold. The highest grain shape magnitudes recorded in the North Carolina fold, however, lie along the overturned fold limb. The final geometry of many folds indicates that hinge plane migration processes are active during compressive deformation events. Numeric, conceptual, and analogue based studies have demonstrated the migration of fold hinges during deformation. However, documentation of these processes in field based studies is rare and limited to techniques that are frequently site specific. Methods proven successful in natural studies include the analysis of superposed folding; the migration of earlier hinge-related features such as fractures, cleavage planes, and boudinaged bedding planes; and the kinematic analysis of syntectonic pressure shadows. The magnitude and orientation of the grain shape ellipsoids calculated for the North Carolina fold indicate that rocks in the overturned limb were once located in the hinge of the fold. Subsequent noncoaxial deformation processes operative during folding resulted in the migration of the hinge to its present orientation and position. This relationship indicates that it is possible to use strain/shape fabric analysis as a test for hinge migration in folds, and that this technique may be more generally applicable in natural settings than previously proposed tests.

Abstract:
A belt of Early Proterozoic rocks crops out in the Cottonwood Cliffs area, northwest Arizona. The belt contains an eastern and a western assemblage separated by the Slate Mountain fault. The western assemblage consists of mafic to felsic metavolcanic rocks, metapelites, and metaconglomerates. The eastern assemblage consists of phyllites, felsic to intermediate metavolcanic rocks, metagraywackes, and metagabbro bodies. The belt is bounded to the east by foliated granodiorite. The Valentine granite intruded the belt on the west and north. Steeply-plunging lineations and fold axes, and northeast-trending vertical foliation dominate the structural fabric. The regional elongation direction is near-vertical, as indicated by mineral and pebble lineations, and is parallel to fold axes. Although only one deformational event is evident, the intensity of that event may have obliterated evidence of any earlier deformation. Tertiary basalts and the Peach Springs Tuff locally overly the metamorphic rocks. Cenozoic normal faults in the area are mostly of minor displacement.

Abstract:
Abstract This book was born of an interest in debates about ‘gnosis’. The subject was inspired by certain analogies between the construction of heresy and the representation of madness described by Michel Foucault in Histoire de la folie à l’âge classique (Madness and Civilization). In different periods one can discern the decision to separate normal from abnormal, the suppression of the voice of the other, the constitution of rationality by means of exclusion. An examination of the ancient sources, on the other hand, confirmed the reversal in the pioneering work of Walter Bauer (1934). Contrary to the thesis canonized by Eusebius of Caesarea, at the beginning there was no doctrinal unanimity in a simple and pure church, but rather a manifest pluralism. Yet Bauer’s book ironically perpetuated the ‘orthodox’ essentialist view that the categories ‘heresy’ and ‘orthodoxy’ represent fixed entities. This investigation aims to demonstrate how the concept of heresy emerges in Justin Martyr, at a time when the very means to diminish conflicts were themselves diverse. This invention creates a concept capable of dominating every current suspected of endangering ecclesial harmony. This polemical tool transforms the tradition of Greek historiography of philosophical schools, by combining it with the apocalyptic theme of diabolical conspiracy. This model is refined by Irenaeus, then modified by Clement of Alexandria and Origen, who are closer to the philosophers. They do not reject everything that comes from ‘heretics’, even as they give pride of place to Greek philosophy. The analysis of the rhetorical processes of refutation also bears on the rules of biblical interpretation put in place to govern exegesis.

Abstract:
This collection brings together leading anthropologists and philosophers working in a wide range of contexts in order to rethink an oft taken for granted concept—the concept of the concept itself. How do we picture what concepts are, what they do, how they arise in the course of everyday life? Challenging conventional approaches that treat concepts as mere tools at our disposal for analysis, or as straightforwardly equivalent to signs to be deciphered, the twelve contributors to Living with Concepts instead looks at the ways in which concepts are already intrinsically embedded in our forms of life, and thus how they constitute the very substrate of our existence as humans who lead lives in language. In other words, attention to our ordinary lives with concepts requires not a movement of ascent from the rough ground of reality into the skies of theory, but rather acceptance of the fact that thinking is congenital to living with and through concepts. Living with Concepts offers a critical and timely intervention into both contemporary philosophy and anthropological theory by deeply unsettling a distinction between thought and reality that is still too often smuggled back into the fold. In its place, the book takes the first step toward an anthropological practice guided by a realistic spirit—one in which the supposed need to grasp reality is replaced by an acknowledgement that we might instead be in its grip.

Abstract:
AbstractFinland has, rather successfully, promoted an image of itself as a model of educational excellence and linguistic equity. This chapter problematises this image by analysing Finnish language education policies at the comprehensive school level. For our analysis we use a three-fold understanding of access as; (a) having the opportunity to participate in language education (getting in); (b) participating in education that is meaningful and effective for the pupil (getting it); and (c) receiving credentials that are societally legitimate and valuable assets (getting out). We elaborate on each aspect of access by debunking three myths for the Finnish context that: (a) Multilingualism is politically valued; (b) the curriculum promotes multilingual education; and (c) the education system offers equal opportunities to all, regardless of language. We conclude with a mixed picture. While initiatives have been put in place to expand participation in language learning and develop multilingual pedagogies, the societal status of national languages and constitutional bilingualism have also, somewhat paradoxically, strengthened monolingual ideologies. Such ideologies have contributed to the erasure of Indigenous and autochthonous languages from education and minimise the position of allochthonous (migrant) languages in curriculum and education. We propose several reforms in teacher education and a more systematic, long term, national supervision of (language) education policy in the service of equitable multilingual education.

Abstract:
AbstractThe chapter explores the nature of higher education in post-Soviet Armenia given the factors prevailing in the system—historical, political, socio-economic and international. Of particular interest is the exploration of the higher education system structure reflected by social needs, economic demands and political goals. Supported by a holistic theoretical framework underpinning three angles of analysis—horizontal and vertical diversity, external diversity as well as the organisational interrelationships—the analysis endeavours to reveal the driving forces that shaped post-Soviet Armenian higher education, the inter-influence that occurred as a result of changes taking place at the macro and micro levels of the higher education system as well as the impact of those changes on the performance of the Armenian HE in general. The results of the analysis are two-fold. First, throughout the decades the Armenian higher education has made major strides and evolved from a uniform into a diverse system responding and accommodating the diverse needs of the society. Second, albeit the strong desire and much investment in the system through a diversity of channels to make the system internationally visible, still more investments are to be made to achieve the desirable goal of international visibility while facing the challenges related to the Soviet legacy, current policymaking and implementation methodology, in particular.

Abstract:
Folded-core sandwich structures have previously been proposed as lightweight, thin-plate building elements. Such structures typically use a Miura-type core pattern and have an efficient load transfer behaviour, however cannot be used for deployable structures as the attachment of face sheets suppresses any core kinematic behaviours. This limitation can be overcome with patterned face sheets that preserve rigid-foldability and form a layered meta-material, here termed a morphing sandwich structure. The relative performance of folded and morphing sandwich structures is unknown, with few studies on the structural behaviour of either configuration. The following paper uses a new digital fabrication methodology to manufacture folded and morphing beam prototypes from 0.9mm thick steel plate. These are subjected to experimental three point bending tests to assess force-displacement behaviour and failure modes. A numerical finite element analysis is conducted to simulate the failure behaviour of the experimental beams. It is seen that the morphing beam has a 44% reduction in strength compared with the folded beam, thought to be attributable to face plate eccentricity and flexibility introduced by the morphing beam hinge connection detail.

Abstract:
Folded plate structures are used for roofing large column-free areas for auditoriums, supermarkets, gymnasiums, hangars for aircraft, and other similar applications. The loads on these structures could cause stresses to go beyond the elastic range. Therefore, a thorough understanding of their elasto-plastic behavior is of utmost importance in designing these structures. An attempt is made to study the elasto-plastic behavior of prismatic metal folded plates by the finite element method using the commercial software, ANSYS. The method is first validated by analyzing typical plates and shells, and comparing them with available solutions in the literature. The elasto-plastic behavior of some prismatic folded plates is then studied, and their force-deflection responses and evolution of plastic zones are evaluated.

Abstract:
This paper compares three models for computing forces caused by gas film squeezed between parallel plates. The models are used to calculate damping forces on an oscillating plate at different oscillation frequencies. The damping forces are then used to calculate nondimensional damping ratios. The damping ratios are used in making comparisons among the models and with experimental data. The experiment used an oscillating MEMS plate suspended by folded springs. The substrate (base) was shaken with a piezoelectric transducer. The plate vibrated as a result, especially at the resonant frequency. The velocities of the suspended plate and of the substrate were measured with a laser Doppler vibrometer and a microscope. Experimental modal analysis gave the damping ratio. To achieve a wide range of squeeze numbers, the experiment was repeated under several different pressures. The measurement was also repeated on an array of plates. Experimental data indicate that, for atmospheric and higher pressures, squeeze-film damping forces can be modeled accurately with a very simple model. For lower pressures in the continuum regime, a more complete model by Veijola (2004) predicts the damping ratio very well.

Abstract:
This paper developed the element technologies for commercialization of the miniature gripper which was considered in the previous paper. There, making use of buckling phenomenon of a long column was tried for the opening and closing mechanism of the miniature gripper. As a result, it was verified which was useful as the opening and closing mechanism of the fingers because it does not need a special mechanism for displacement enlargement, so unique, original and simple. The results obtained are as follows. (1) In the manufacturing of a multi-finger hand, the way for a blank cut from the elastic plate by wire-cut electrical discharge machine to be bent like a telescopic umbrella folded was devised. According to the way, not only will the finger with uneven division or variant be manufactured, but also could further miniaturization be made in similarity. (2) As for the adjustment technique of the gripping force, a positioning nut enabled translational displacement of a screw axis nut to be mechanically set. Consequently, the gripping force changes corresponding to the closing amount of the finger with 0 to maximum (solid contact). (3) In the application of this opening and closing mechanism, a pair of electric tweezers, which finger is automatically opened and closed approximately 5mm by one way rotation drive of a motor, was prototyped. Reciprocating translational displacement h0 of the hand center was realized by simple spherical cam mechanism comprising two small steel balls only with eccentricity each other which are in contact. Radii rc and rf of the steel balls of the prototype are 0.5mm, maximum lift h0 0.3mm and eccentricity 0.357mm.

Quasi-static loading in two in-plane direction is selected to obtain the deformation and plateau stress. The unique collapse modes and plateau state are obtained and discussed. Compared with the conventional honeycombs, the in-plane strength of the two folded honeycombs is improved significantly. The negative Poisson’s ratio effect and buckling-restrained mechanism are introduced to illustrate the improvement. It is summarized that plateau stress under in-plane loading is improved with the included angle of miura pattern decrease for the local buckling is restrained. The folded auxetic honeycomb has the best in-plane strength for its presented negative Poisson’s ratio in two loading cases.

Abstract:
The Kipawa rare-earth element (REE) deposit is located in the Parautochton zone of the Grenville Province 55 km south of the boundary with the Superior Province. The deposit is part of the Kipawa syenite complex of peralkaline syenites, gneisses, and amphibolites that are intercalated with calc-silicate rocks and marbles overlain by a peralkaline gneissic granite. The REE deposit is principally composed of eudialyte, mosandrite and britholite, and less abundant minerals such as xenotime, monazite or euxenite. The Kipawa Complex outcrops as a series of thin, folded sheet imbricates located between regional metasediments, suggesting a regional tectonic control. Several hypotheses for the origin of the complex have been suggested: crustal contamination of mantle-derived magmas, crustal melting, fluid alteration, metamorphism, and hydrothermal activity. Our objective is to characterize the mineralogical, geochemical, and isotopic composition of the Kipawa complex in order to improve our understanding of the formation and the post-formation processes, and the age of the complex. The complex has been deformed and metamorphosed with evidence of melting-recrystallization textures among REE and Zr rich magmatic and post magmatic minerals. Major and trace element geochemistry obtained by ICP-MS suggest that syenites, granites and monzonite of the complex have within-plate A2 type anorogenic signatures, and our analyses indicate a strong crustal signature based on TIMS whole rock Nd isotopes. We have analyzed zircon grains by SEM, EPMA, ICP-MS and MC-ICP-MS coupled with laser ablation (Lu-Hf). Initial isotopic results also support a strong crustal signature. Taken together, these results suggest that alkaline magmas of the Kipawa complex/deposit could have formed by partial melting of the mantle followed by strong crustal contamination or by melting of metasomatized continental crust. These processes and origins strongly differ compare to most alkaline complexes in the world. Additional TIMS and LA-MC-ICP-MS analyses are planned to investigate whether all lithologies share the same strong crustal signature.

BOND-SLIP TESTING AND PERFORMANCE EVALUATION OF SEMI-RIGID FLANGE FOLDED WEB SHEAR KEYS. The Hong Kong Institute of Steel Construction, December 2022. http://dx.doi.org/10.18057/ijasc.2022.18.4.3.

Abstract:
The shear key is crucial to the overall mechanical performance of the structure. A new type of semi-rigid connector-flange folded web shear key was proposed to determine the effective unity of higher bearing capacity and deformation. A total of five groups of specimens were designed, and the push-out test method was used to evaluate the ultimate bearing capacity, bond-slip process, failure mode, and strain distribution of the new shear key. The results show that before sliding, the embedded effect of the concrete and shear key is significant, and it has a significant sliding stiffness. After sliding, the steel plate in the middle of the opening of the outer folded plate buckles, which shows certain semi-rigid characteristics. Compared with equal-area studs, the bearing capacity of the new shear key is increased by more than 40%, and the deformation capacity exceeds 60 %, indicating good bond-slip performance. The constraint range of the shear key is greatly improved compared with the stud, and a trapezoidal area of constraint centered on the shear key is formed, accounting for more than half of the area of the concrete slab. Based on an experimental study, a practical calculation method of ultimate bearing capacity of the shear key is proposed, which can meet engineering safety requirements. Based on the analysis of bond-slip characteristics of different forms of shear keys, compared with the rigid T-shaped shear key, the slip load and ultimate bearing capacity of the new shear key are found to be increased by 39 % and 74 %, respectively, and the deformation capacity is increased more than 10-fold. Compared with the flexible stud shear connectors, the sliding load is increased by 86 %, the ultimate bearing capacity is increased more two-fold, and the stiffness is increased by nearly five times. The device exhibits good comprehensive performance.
