Abstract:

While much of the linear theory of structural dynamics has been codified in numerous computer software, important problems remain such as inverse methods (modal synthesis or system identification) and optimization problems. Nonlinear problems, however, are a fertile ground for new research, especially those involving large deformations (e.g., crash simulation) and material nonlinearities. Structure interaction problems will continue to be a fruitful area of research including fluid-structure dynamics and interaction with acoustic noise, thermal fields, soils, and electromagnetic forces. For example, new knowledge about unsteady flows around bluff bodies is needed to make significant progress with dynamic interaction problems with bridge and building structures in unsteady winds. A new field which shows great promise for application is the theory of feedback control of flexible structures. Advances in this area could pay off in near-space engineering and robotics. The training of new researchers with backgrounds in both structural dynamics and control theory and experience is a high priority for the control-structure field, however.

Abstract:

Rotavirus double-layered particles (DLPs) are formed immediately following entry of virions into a host cell. To study the structural dynamics of actively transcribing rotavirus DLPs, we implemented high resolution imaging procedures along with automated computing routines to visualize mRNA synthesis at the nanoscale. Our combined technologies demonstrate a new approach to monitor dynamic structural processes, such as capsid rearrangements, that may be applied to the study of other viruses.

Abstract:

The issue of structural changes is poorly researched and unresolved in the assessment of sustainable development in the countries of the world and remains relevant for many years. The purpose of the article was to clarify the content of the issue of structural changes and justify the method of assessing the structural dynamics of the country’s stable development to ensure its objectivity and reliability. To achieve the goal, an abstract-logical method was used to determine the degree of solving the problem of assessing structural changes in the stable development of countries and to develop a structural dynamic benchmark. The method of constructing an integral key figure of structural dynamics was used to determine the level of a country’s stable development using the example of Ukraine. The regression analysis was used to determine the dependence of the structural dynamics of stable development on main factors. It was found that the results of the structural dynamics assessment of the stable development depend on the structural dynamic benchmark, as the state is compared with it. This structural dynamic benchmark of the stable development of countries is the main assessment tool. The new structural dynamic benchmark for the stable development of developing countries is substantiated. In the calculation of the integral key figure of the structural dynamics of stable development, the base rates of macroeconomic key figures that reflect this development were used. It is proposed to determine the factors influencing the integral key figure of the structural dynamics of stable development. The range of [0.28; 0.35] represents the low level of structural dynamics in Ukraine’s stable development. The practical value of the proposed approach to structural change assessment in the country’s stable development lies in the possibility of rapid diagnosis and monitoring of these changes for early correction of the negative consequences of phenomena that slow down development

Abstract:

Abstract Structure design is a mixture of art and science, combining the experienced engineer’s intuitive feeling of statics and material. In the engineering practice, it is not exact enough to design a structure only by considering the constant loading. Time-varying loading such as earth-quake, wind loading, bomb blast loading, vortex should be taken into consideration in the practical engineer problems. If structure is subjected with a time-varying loading, the response is vibration. This article is going to show how to deal with some typical types of vibration such as free vibration analysis of SDOF equation of motion, the undamped free vibration, the damped free vibration and vibration control Further, it will explain structural dynamic responses under the periodic loading, impulsive loading. Air crash, building collapse will be predictable and this will save people’s lives and decreasing economic loss. The methodology of dynamic analysis will be applicated in the real world of structure design.

Abstract:

Due to the nature of real-world problems in civil engineering, students have had limited hands-on experiences in structural dynamics classes. To address this challenge, this paper aims to bring real-world problems in structural dynamics into classrooms through a new interactive learning tool that promotes physical interaction among students and enhances their engagement in classrooms. The main contribution is to develop and test a new interactive computing system that simulates structural dynamics by integrating a dynamic model of a structure with multimodal sensory data obtained from mobile devices. This framework involves integrating multiple physical components, estimating students’ motions, applying these motions as inputs to a structural model for structural dynamics, and providing students with an interactive response to observe how a given structure behaves. The mobile devices will capture dynamic movements of the students in real-time and take them as inputs to the dynamic model of the structure, which will virtually simulate structural dynamics affected by moving players. Each component of synchronizing the dynamic analysis with motion sensing is tested through case studies. The experimental results promise the potential to enable complex theoretical knowledge in structural dynamics to be more approachable, leading to more in-depth learning and memorable educational experiences in classrooms.

Abstract:

This paper describes the development of a structural dynamics add-on to WEC-Sim, an open-source code dedicated to the dynamic analysis of Wave Energy Converters (WECs). When calculating the dynamic response of a body, WEC-Sim by default uses a rigid body dynamics approach. Such an approach ignores the potential effects of structural deformation on the WEC, which can in turn affect e.g. the distributed loads across the WEC and / or the individual (point) load sources that depend on the dynamic response of the WEC. Following a similar approach to tools used in the offshore wind industry, a structural dynamic add-on was developed using Code_Aster as the Finite Element (FE) solver to enable coupled hydro-elastic, time-domain analysis. The add-on was developed and tested using an example Oscillating Wave Surge Converter (OWSC) WEC model, currently being developed as part of the H2020 MegaRoller project. In the examples studied, the inclusion of structural dynamics is shown to affect the estimated peak Power Take-Off (PTO) loads, with variations in PTO force of over 10% being observed when structural dynamics are considered in the analysis.

Abstract:

RNA-protein complexes (RNPs) are essential components in a variety of cellular processes, and oftentimes exhibit complex structures and show mechanisms that are highly dynamic in conformation and structure. However, biochemical and structural biology approaches are mostly not able to fully elucidate the structurally and especially conformationally dynamic and heterogeneous nature of these RNPs, to which end single molecule Förster resonance energy transfer (smFRET) spectroscopy can be harnessed to fill this gap. Here we summarize the advantages of strategic smFRET studies to investigate RNP dynamics, complemented by structural and biochemical data. Focusing on recent smFRET studies of three essential biological systems, we demonstrate that investigation of RNPs on a single molecule level can answer important functional questions that remained elusive with structural or biochemical approaches alone: The complex structural rearrangements throughout the splicing cycle, unwinding dynamics of the G-quadruplex (G4) helicase RHAU, and aspects in telomere maintenance regulation and synthesis.

Abstract:

There is an increasing reliance in the engineering community on the use of mathematical models to characterize physical system behavior. This is happening even though mathematical models rarely simulate real system behavior perfectly. Due to this reliance, we require objective, well-founded mathematical techniques for model validation. This paper develops a formal approach to the validation of mathematical models of structural dynamics systems. It uses a probabilistic/statistical approach to the characterization of an important measure of behavior of dynamic systems subjected to random excitations, and seeks to validate a mathematical model in a statistical sense. An example is presented.

Abstract:

Nucleosomes and chromatin control eukaryotic genome accessibility and thereby regulate DNA processes, including transcription, replication, and repair. Conformational dynamics within the nucleosome and chromatin structure play a key role in this regulatory function. Structural fluctuations continuously expose internal DNA sequences and nucleosome surfaces, thereby providing transient access for the nuclear machinery. Progress in structural studies of nucleosomes and chromatin has provided detailed insight into local chromatin organization and has set the stage for recent in-depth investigations of the structural dynamics of nucleosomes and chromatin fibers. Here, we discuss the dynamic processes observed in chromatin over different length scales and timescales and review current knowledge about the biophysics of distinct structural transitions.

Abstract:

Since structure is not completely static, but more or less changing, it appears appropriate to see it dynamically as process. More specifically, each particular structure can be conceived of as a combination of morphogenetic processes. These process combinations may change during development and evolution, during ontogeny and phylogeny. Evolutionary processes, or more specifically modes of morphological transformation, can be seen more dynamically when conceptualized as changes in process combinations. These evolutionary dynamics are illustrated by examples of the evolutionary processes of several schemes such as Zimmermann's scheme (heterochrony, heterotopy, heteromorphy), Takhtajan's scheme (prolongation, abbreviation, deviation) and other processes such as homeosis. Process morphology, which deals with the diversity of plant form in terms of process combinations (instead of structural categories such as root, stem, and leaf), provides a dynamic integration of development and evolution in terms of process combinations and their changes. In other words, the (developmental) dynamics of process combinations representing structures is seen undergoing further (evolutionary) dynamics. Hence, there are (evolutionary) dynamics of the (developmental) dynamics. Key words: plant morphogenesis, evolutionary processes, homology, heterochrony, neoteny, homeosis.

Abstract:

Governments render decisions on how resources and values are allocated in a society. In the United States, Congress is the institution in which most of the key allocating decisions are made. To the extent the U.S. political system is integrated, the coalitions that form around the issues debated in Congress should be reflected in the coalitions that support presidential candidates and those that support the major political parties. We formulate a spatial theory of political change in which new ideological cleavages appear in congressional behavior and presidential elections and gradually reorganize the mass party base. The theory leads us explicitly to consider the question of dealignment and to specify conditions under which the parties will lose support from voters.

Abstract:

This paper discusses the main issues of Uncertainty Analysis (UA) in general and also argues and illustrates its particular relevance to structural dynamics. Brief descriptions are given of the most prevalent of the many frameworks for uncertainty representation. The three main uncertainty-related problems of relevance to structural dynamics are then discussed, namelyquantification,fusionandpropagation. In order to illustrate the application of ideas of UA in a realistic scenario, there then follows a case study conducted on an aerospace structure, namely the wing of a Gnat trainer aircraft. The case study considers evidence-based classifiers as an alternative to probabilistic classifiers for the problem of damage location within the context of Structural Health Monitoring. Dempster-Shafer theory is employed to construct neural network classifiers with the potential to admit ignorance, rather than misclassify.

Abstract:

The published work on analytical ("mathematical") and computer-aided, primarily finite-element-analysis (FEA) based, predictive modeling of the dynamic response of electronic systems to shocks and vibrations is reviewed. While understanding the physics of and the ability to predict the response of an electronic structure to dynamic loading has been always of significant importance in military, avionic, aeronautic, automotive and maritime electronics, during the last decade this problem has become especially important also in commercial, and, particularly, in portable electronics in connection with accelerated testing of various surface mount technology (SMT) systems on the board level. The emphasis of the review is on the nonlinear shock-excited vibrations of flexible printed circuit boards (PCBs) experiencing shock loading applied to their support contours during drop tests. At the end of the review we provide, as a suitable and useful illustration, the exact solution to a highly nonlinear problem of the dynamic response of a "flexible-and-heavy" PCB to an impact load applied to its support contour during drop testing.

The treatment of structural parameters as random variables has been the subject of structural dynamicists and designers for many years. Several problems have been involved during the last few decades and resulted in new theorems and interesting phenomena. This paper reviews a number of topics pertaining to structural dynamics with parameter uncertainties. These include direct problems such as random eigenvalues and random responses of discrete and continuous systems. The impact of these problems on related areas of interest such as sensitivity of structural performance to parameter variations, design optimization, and reliability analysis is also addressed. The paper includes the results of experimental investigations, the phenomenon of normal modes localization, and the effect of mistuning of turbomachinery blades on their flutter and forced response characteristics.
