Materials and fabrication techniques are developed that lead to the successful fabrication of multilayer composite photonic bandgap fibers. The pertinent background in electromagnetic theory of multilayer dielectric mirrors and optical fibers is surveyed. Materials properties constraints are outlined, with emphasis on those constraints related to processing strategy and ultimate target length scale. Interfacial energy is measured in a chalcogenide glass / organic polymer composite system selected for fiber fabrication. A classical capillary instability model is employed to predict the feasibility of fiber fabrication based on material properties; from this model, quantitative materials selection criteria related to ultimate length scale are derived. Good agreement is found between the calculated materials selection criteria and controlled fiber experiments. The fiber fabrication techniques are described and analyzed; chalcogenide film deposition is characterized using Raman and electron microprobe spectroscopy, and heat transfer during fiber drawing is modeled using a commercial finite-element software package. The developed materials and fabrication processes are used to perform two case studies in novel photonic bandgap fiber fabrication; the first case study deals with externally reflecting omnidirectional 'mirror-fibers', while the second deals with hollow- core light transmitting fibers. The reflecting mirror-fibers consist of a tough polymer core surrounded by multiple coaxial submicron-thick layers of a high-refractive-index glass and a low-index polymer; these layers reflect external light from all incident angles and polarizations in the mid-IR range.
(cont.) Large directional photonic gaps and high reflection efficiencies that are comparable to the best metallic reflectors were measured. In the second case study, the light-transmitting fibers consist of a hollow air core surrounded by multiple alternating layers of the same materials, resulting in large infrared photonic bandgaps. Optical energy is strongly confined in the hollow fiber core, enabling light guidance in the fundamental and up to fourth-order gaps. These gaps are placed at selectable wavelengths within a large selection range, from 0.75 to 10.6 m. Tens of meters of hollow photonic bandgap fibers designed for 10.6 pgm radiation transmission are fabricated. We demonstrate transmission of carbon dioxide (CO2) laser light with high power-density through more than 4 meters of hollow fiber and measure the losses to be less than 1.0 dB/m at 10.6 microns. Thus, fiber waveguide losses are suppressed by orders of magnitude compared to the intrinsic fiber material losses.

Silicon carbide (SiC) has been proposed as an alternative to zirconium alloys used in current light water reactor (LWR) fuel cladding because it exhibits superior corrosion characteristics, high-temperature strength, and a 1000°C higher melting temperature, all of which are important during a loss of coolant accident (LOCA). To improve the performance of SiC cladding, a multilayered architecture consisting of layers of monolithic SiC (mSiC) and SiC/SiC ceramic matrix composite (CMC) has been proposed. In this work, the mechanical performance of both the tubing and the endplug joint of two-layer SiC cladding is investigated under conditions associated with the LOCA. Specifically, SiC cladding mechanical performance is investigated after exposure to 1,400°C steam and after quenching from 1,200°C into either 100°C or 90°C atmospheric-pressure water. The samples consist of two-layer SiC, with an inner SiC/SiC CMC layer and an outer monolith SiC layer. The relationship between mechanical performance and sample architecture is investigated through ceramography and internal void characterization. The two-layered SiC cladding design offered an as-received failure hoop stress of about 600 MPa, with little strength reduction due to thermal shock, and the tube failure hoop stress remained above 200 MPa after 48 hour high-temperature steam oxidation. The cladding showed pseudo-ductile behavior and failed in a non-frangible manner. The designs investigated for joint strength offered as-received burst strength above 30 MPa, although the impact of thermal shock and oxidation showed possible dependence on architecture. Overall, the cladding showed promising accident-tolerant performance. Because the implementation of SiC is complicated by the need for an open gap and low plenum pressure, thorium-based mixed oxides (MOX) are a promising fuel for SiC cladding because they have higher thermal conductivity and lower fission gas release (FGR). Previous efforts at MIT have modified the FRAPCON code to include thorium MOX fuel. In this work, the fission gas release and thermal conductivity models of FRAPCON-3.4-MIT are validated against published data. The results of this validation indicate a need to update the FGR model, which was accomplished in this work.

Повний текст джерелаThe present study deals with the development of a numerical model to evaluate the ballistic performance of a polymer/metal multilayer structure sintered by SPS. The materials are an aluminum alloy 7020 and an amorphous thermoplastic polyimide which are then assembled using an epoxy resin. The mechanical behavior of these three materials has been studied over wide ranges of strain rates (from 0.0001 / s to 50,000 / s) and temperatures (from -70 °C to 500 °C) corresponding to the extreme conditions encountered during impacts at high velocities. In order to improve the accuracy of the results, analytical approaches have been developed both for the modeling of the metal and for the polymers. After the calibration of the models, these models were implemented in ABAQUS® / Explicit (finite elements) via VUMAT subroutines in FORTRAN code. Ball impact tests at high velocities were performed on monolayer targets to validate numerical models. Numerous configurations of multilayer composites were then studied numerically and their ballistic performances have been compared

Повний текст джерелаNowadays, composite materials make it possible to reduce the mass of parts and are widely used in the aerospace, aeronautics and automotive industries. In addition, the multilayered reinforcement of composites allows the design of thick structures such as the fan blades of aircraft engines. However, many defects can occur during the forming process of multilayered reinforcements, such as the wrinkling problem. Research on the formation of wrinkles, as well as on the tufting technology to improve the mechanical property of multilayered reinforcements in the direction of thickness are presented in this work. The first part of this report is a study of the formation of the wrinkles of multilayered reinforcements subjected to out-of-plane bending. Firstly, the influence of the different orientations of the layers on the formation of wrinkles is explored. The relationship between the load applied to the fabric and the creation of wrinkles is thus shown. The second chapter compares two types of weaving pattern on the drapability of the composite. The third part consists of developing two numerical models adapted to simulate the forming of tuft-bonded composite reinforcements. These approaches involve the use of a stress resultant shell element to represent each layer of reinforcement and bar elements to represent the tufting yarn. These models require a specific contact algorithm to manage the interaction between the reinforcement and the tufting yarn. Finally, the last part consists of validating the models by comparing simulations and experiments

Повний текст джерелаThis thesis focuses on the evaluation of the quality of adhesion in metal/adhesive/carbon-epox: structural assemblies used in the automotive and aerospace industry. The quality of the bonding i assessed by non-destructive methods using ultrasonic guided waves of the Lamb and SH types. A nev finite element numerical model was developed during this work: it is an interphase rheological mode that allows the dispersion curves of the guided modes to be plotted in the samples studied. It als( makes it possible to predict the evolution of the amplitude of these modes and the distribution o energy in the structure according to the level of adhesion or the presence of a kissing bond type defect. Samples with known and controlled adhesion levels are made with the help of physico chemists, 'where the epoxy is partially or totally crosslinked, and where the substrate/adhesivl interface has undergone different chemical treatments. In particular, samples are studied whos degradation of the bonding in the structure is not symmetrical. The experimental results are compare( with those from the numerical model. These results show that it is possible to characterize two clos levels of adhesion and also to determine on which interface (metal/adhesive or composite/adhesive the bonding has been degraded. The use of a measurement bench with electromagnetic acousti( transducers (EMAT) allowed thè study of the amplitude of the SH modes. Significant variations in th( amplitude of some modes have been observed when the wave passes from an area of good adhesioi to an area where the bonding is degraded

Caratterizzazione in vitro della precisione di accoppiamento e delle proprietà meccaniche." Doctoral thesis, Università degli studi di Padova, 2016. http://hdl.handle.net/11577/3424453.
Повний текст джерелаL’obiettivo di questo lavoro è studiare alcuni aspetti della moderna filiera produttiva digitale di manufatti protesici in campo dentale: dalla realizzazione dell’impronta ottica, direttamente nel cavo orale, alla finalizzazione del dispositivo protesico individualizzato per il paziente. La motivazione di questo studio risiede nell’esigenza sempre più sentita da parte di tutto il mondo dentale di ottimizzare e modernizzare i flussi di lavoro che sono ancora essenzialmente artigianali. Sfruttando le moderne tecnologie digitali, che si stanno rapidamente diffondendo in campo dentale, è possibile ottenere prodotti finiti di più alto standard qualitativo a fronte di costi di realizzazione più contenuti a condizione di diffondere ai clinici ed agli odontotecnici le conoscenze e le competenze necessarie all’utilizzo ottimale. In particolare sono stati presi in considerazione i seguenti temi di particolare rilevanza clinica: - la tecnologia di scansione ottica intraorale: sono state indagate le specificità operative e le prestazioni tecniche in particolare riferimento all’impiego per edentulie totali riabilitate mediante impianti, - i materiali ceramici innovativi, lavorabili mediante tecnologia Cad-Cam ed impiegati per realizzare protesi a ponte su denti naturali di tipo multilayer metalfree. E’ stato inoltre indagato un innovativo materiale in resina composita, anch’esso utilizzabile con tecnologia Cad-Cam ed impiegato per la realizzazione di corone singole su impianti. La revisione della letteratura tecnico scientifica, ha suggerito gli obbiettivi e gli aspetti metrologici del programma di ricerca sperimentale da condurre. Le indagini hanno riguardato aspetti di precisione ed accuratezza della lettura ottica della posizione degli impianti, di precisione geometrica di accoppiamento di protesi multilayer metal free, di resistenza meccanica di diversi tipologie di materiali e di adesione tra un recente composito a matrice resinosa, denominato Resin Nano-Ceramic (RNC) e zirconia; hanno previsto l’introduzione di strumenti e metodi consolidati in campo tecnico-scientifico, adatti a caratterizzare i processi di fabbricazione utilizzati, i materiali impiegati e i dispositivi realizzati. Più in dettaglio, l’attività ha riguardato: 1. lo studio, in termini di prestazioni metrologiche, del processo di acquisizione effettuato mediante il sistema di scansione True Definition Scanner su un campione clinico riproducente un'arcata completamente edentula riabilitata con 6 impianti; 2. la verifica della precisione geometrica di accoppiamento delle componenti, sotto e sovrastruttura, di protesi metalfree multilayer realizzate con materiali ceramici diversi (zirconia-disilicato di litio) prodotte mediante tecnologia Cad-Cam, e assemblate da due operatori diversi; l’assemblaggio/unione delle componenti, dei singoli ponti, viene invece realizzato manualmente dall’odontotecnico con tecnica totalmente artigianale; 3. l’analisi del comportamento meccanico, statico, delle protesi metalfree multilayer, citate al punto 2, confrontate con un altro tipo di protesi multilayer (provenienti dagli stessi progetti Cad) ma costituite da zirconia e ceramica feldspatica (RLT), 4. l’analisi mediante prova meccanica, statica e a fatica, della resistenza di un innovativo materiale in resina composita fornito in blocchetti per lavorazione Cad-Cam: Lava Ultimate. Questo nuovo materiale composito presenta, rispetto ad altri materiali estetici quanto a proprietà meccaniche dichiarate, (modulo di Young), un comportamento più simili al dente naturale. In quest’ottica, è stato utilizzato per realizzare corone singole su impianti, confrontando due modalità diverse di impiego: cementando una corona realizzata con questo composito e prodotta con tecnologia Cad-Cam direttamente su un pilastro standard in titanio fornito dall’industria, o realizzando con lavorazione Cad-Cam una sottostruttura in zirconia individualizzata e cementando su quest’ultima la corona in composito; 5. la verifica delle capacità adesive tra zirconia e Lava Ultimate, utilizzando due diversi cementi resinosi mediante test di taglio. Sulla base dei risultati delle campagne sperimentali condotte in questo studio è possibile affermare che: 1 le tecnologie di impronta ottica digitale intraorale sono in grado di rispondere ai requisiti clinici di precisione anche nel caso di arcate complete riabilitate su impianti, 2. le protesi multilayer metalfree, realizzate con tecnologia Cad-Cam secondo i requisiti di precisione propri dal workflow digitale, risentono dell’intervento di assemblaggio finale che esegue l’odontotecnico, con conseguente riduzione delle qualità di precisione stabilite in fase progettuale, 3. i ponti multilayer metalfreee presentano valori di resistenza alla frattura superiori o uguali ai valori minimi riportatati dalla letteratura scientifica 4. le corone su impianti realizzate con l’innovativo materiale composito, sottoposto a prove di resistenza statica e a fatica, quando cementate su un moncone individualizzato in zirconia, hanno caratteristiche meccaniche superiori alla soluzione più economica, che prevede la cementazione della corona direttamente ad un pilastro standardizzato in titanio. 5. l’utilizzo di cementi adesivi per cementare Lava Ultimate su zirconia, ha permesso di evidenziare comportamenti opposti per quanto riguarda le forze di adesione misurate con il test di taglio.

Marchetti, Fabien. "Modelling and characterisation of anisotropic multilayered plates on a wide frequency range." Thesis, Lyon, 2019. http://www.theses.fr/2019LYSEI130.
Повний текст джерелаThis PhD thesis concerns the modelling and the dynamic characterisation of anisotropic multilayered structures. In the first chapter, a classification of some analytical models and experimental methods of characterisation is presented in the form of a bibliographical synthesis where the main published results are gathered. The second chapter introduces an extension of an equivalent model of multilayered structures to the case of anisotropic materials. This model describes the first dispersion curves of the structure and considers the shear phenomena that can affect the bending mode in high frequencies. The main advantage of the model lies in its simplicity and rapidity thanks to a number of kinematic variables independent of the number of layers. The characteristics of the multilayer are defined by the 5 flexural rigidities of a thin equivalent plate which is compared to the multilayer. The results of the model are validated by means of an experimental study on carbon fiber composite plates. A particular interest is dedicated to the modelling of structural damping. An energetic loss factor, based on a temporal and spatial definition of the attenuation, is compared to an equivalent one. A new definition of the spatial attenuation is suggested for high damped structures and is compared to literature. In the third chapter, the methodology of the characterisation technique CFAT is adapted for anisotropic plates. This inverse method is based on the displacement field analysis of the structure and has, by means of its local aspect, relevant advantages for industrial applications. This adaptation is, as a first step, introduced for the identification of sources (initial objective of the method) and applied, in a second step, for the characterisation. Several numerical and experimental applications are presented to validate the results of the method. Finally, the fourth chapter deals with the experimental characterisation of a honey comb sandwich on a high frequency range (1 to 300 kHz). The complex dynamic behaviour of this thick structure is described through the promissing results given by the simulations of our model and the estimations of RIC. These results are also compared to the ones of a reference model and other characterisation methods
Crisafulli, Daniela. "Advanced modelling of multilayered composites and functionally graded structures by means of Unified Formulation." Thesis, Paris 10, 2013. http://www.theses.fr/2013PA100055/document.
Повний текст джерелаMost of the engineering problems of the last two centuries have been solved thanks to structural models for both beams, and for plates and shells. Classical theories, such as Euler-Bernoulli, Navier and De Saint-Venant for beams, and Kirchhoff-Love and Mindlin- Reissner for plates and shells, permitted to reduce the generic 3-D problem, in onedimensional one for beams and two-dimensional for shells and plates. Refined higher order theories have been proposed in the course of time, as the classical models do not consent to obtain a complete stress/strain field. Carrera Unified Formulation (UF) has been proposed during the last decade, and allows to develop a large number of structural theories with a variable number of main unknowns by means of a compact notation and referring to few fundamental nuclei. This Unified Formulation allows to derive straightforwardly higher-order structural models, for beams, plates and shells. In this framework, this thesis aims to extend the formulation for the analysis of Functionally Graded structures, introducing also the thermo-mechanical problem, in the case of functionally graded beams. Following the Unified Formulation, the generic displacements variables are written in terms of a base functions, which multiplies the unknowns. In the second part of the thesis, new bases functions for shells modelling, accounting for trigonometric approximation of the displacements variables, are considered

Повний текст джерелаThe full utilization of the light weight potential in the dimensioning of multilayer fiber reinforced composites requires suitable optimization tools, since a large number of design variables has to be taken into account. In this work, optimization algorithms and strategies for the solution of scientific questions for industrial applications are developed and evaluated in the design of corresponding fiber-plastic composites. In order to show the wide range of applications, three different representative topics have been chosen. It will carry out a strength optimization for multilayer composites with regard to a type-related failure criterion, devolop a damping model for material characterization and established a bivalent optimization strategy for the design of wound high-pressure vessels. The developed methods are based on stochastic natural-analog optimization heuristics, since the considered tasks are not convex and such methods can be used in a very flexible manner
