Book excerpt: Aviation safety can be greatly enhanced by the expeditious use of computer simulations of crash impact. Unlike automotive impact testing, which is now routine, experimental crash tests of even small aircraft are expensive and complex due to the high cost of the aircraft and the myriad of crash impact conditions that must be considered. Ultimately, the goal is to utilize full-scale crash simulations of aircraft for design evaluation and certification. The objective of this publication is to describe "best practices" for modeling aircraft impact using explicit nonlinear dynamic finite element codes such as LS-DYNA, DYNA3D, and MSC.Dytran. Although "best practices" is somewhat relative, it is hoped that the authors' experience will help others to avoid some of the common pitfalls in modeling that are not documented in one single publication. In addition, a discussion of experimental data analysis, digital filtering, and test-analysis correlation is provided. Finally, some examples of aircraft crash simulations are described in several appendices following the main report.Fasanella, Edwin L. and Jackson, Karen E.Langley Research CenterAIRCRAFT SAFETY; NONLINEARITY; FINITE ELEMENT METHOD; AIRCRAFT ACCIDENTS; COMPUTERIZED SIMULATION; CRASHES; IMPACT TESTS; AIRCRAFT DESIGN; AUTOMOBILES; CERTIFICATION; CORRELATION; COSTS; FLIGHT SAFETY

Available in PDF, EPUB and Kindle. Book excerpt: Commissioned by the Society for Modeling and Simulation International (SCS), this needed, useful new ‘Body of Knowledge’ (BoK) collects and organizes the common understanding of a wide collection of professionals and professional associations. Modeling and simulation (M&S) is a ubiquitous discipline that lays the computational foundation for real and virtual experimentation, clearly stating boundaries—and interactions—of systems, data, and representations. The field is well known, too, for its training support via simulations and simulators. Indeed, with computers increasingly influencing the activities of today’s world, M&S is the third pillar of scientific understanding, taking its place along with theory building and empirical observation. This valuable new handbook provides intellectual support for all disciplines in analysis, design and optimization. It contributes increasingly to the growing number of computational disciplines, addressing the broad variety of contributing as well as supported disciplines and application domains. Further, each of its sections provide numerous references for further information. Highly comprehensive, the BoK represents many viewpoints and facets, captured under such topics as: Mathematical and Systems Theory Foundations Simulation Formalisms and Paradigms Synergies with Systems Engineering and Artificial Intelligence Multidisciplinary Challenges Ethics and Philosophy Historical Perspectives Examining theoretical as well as practical challenges, this unique volume addresses the many facets of M&S for scholars, students, and practitioners. As such, it affords readers from all science, engineering, and arts disciplines a comprehensive and concise representation of concepts, terms, and activities needed to explain the M&S discipline. Tuncer Ören is Professor Emeritus at the University of Ottawa. Bernard Zeigler is Professor Emeritus at the University of Arizona. Andreas Tolk is Chief Scientist at The MITRE Corporation. All three editors are long-time members and Fellows of the Society for Modeling and Simulation International. Under the leadership of three SCS Fellows, Dr. Ören, University of Ottawa, Dr. Zeigler, The University of Arizona, and Dr. Tolk, The MITRE Corporation, more than 50 international scholars from 15 countries provided insights and experience to compile this initial M&S Body of Knowledge.

This book was released on 2020-11-18 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most high performance structures require the development of a generation of new materials, which can more easily resist a range of external stimuli or react in a non-conventional manner. Formed of research works presented at the 10th International Conference on High Performance and Optimum Design of Structures and Materials, the included papers cover issues involving advanced types of structures, particularly those based on new concepts or new materials and their system design. Contributions highlight the latest developments in design, optimisation, manufacturing and experimentation. There is also a focus on the search for higher performance sustainable materials. Particular emphasis is placed on intelligent structures and materials as well as the application of computational methods for their modelling, control and management. Optimisation problems are also covered, including those related to the size, shape and topology of structures and materials. Optimisation techniques have much to offer to those involved in the design of new industrial products. The development of new algorithms and the appearance of powerful commercial computer codes with easy to use graphical interfaces has created a fertile field for the incorporation of optimisation in the design process in all engineering disciplines.

This book was released on 2022-02-08 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Big data thrives on extracting knowledge from a large number of data sets. But how is an application possible when a single data set is several gigabytes in size? The innovative data compression techniques from the field of machine learning and modeling using Bayesian networks, which have been theoretically developed and practically implemented here, can reduce these huge amounts of data to a manageable size. By eliminating redundancies in location, time, and between simulation results, data reductions to less than 1% of the original size are possible. The developed method represents a promising approach whose use goes far beyond the application example of crash test simulations chosen here.

Book excerpt: A novel theory of organizational and technological change, illustrated by an account of the development and implementation of a computer-based simulation technology. Every workday we wrestle with cumbersome and unintuitive technologies. Our response is usually "That's just the way it is." Even technology designers and workplace managers believe that certain technological changes are inevitable and that they will bring specific, unavoidable organizational changes. In this book, Paul Leonardi offers a new conceptual framework for understanding why technologies and organizations change as they do and why people think those changes had to occur as they did. He argues that technologies and the organizations in which they are developed and used are not separate entities; rather, they are made up of the same building blocks: social agency and material agency. Over time, social agency and material agency become imbricated--gradually interlocked--in ways that produce some changes we call "technological" and others we call "organizational." Drawing on a detailed field study of engineers at a U.S. auto company, Leonardi shows that as the engineers developed and used a a new computer-based simulation technology for automotive design, they chose to change how their work was organized, which then brought new changes to the technology.Each imbrication of the social and the material obscured the actors' previous choices, making the resulting technological and organizational structures appear as if they were inevitable. Leonardi suggests that treating organizing as a process of sociomaterial imbrication allows us to recognize and act on the flexibility of information technologies and to create more effective work organizations.

Book excerpt: In May 2009, the U.S. announced plans to increase the Nat. Highway Traffic Safety Admin. (NHTSA) corp. average fuel econ. (CAFE) standards and establish the EPA greenhouse gas emissions standards for vehicles. NHTSA redesigned CAFE standards for light trucks for model years 2008-11. Experts raised questions about the rigor of the computer modeling NHTSA used to develop these standards. This report reviewed: (1) the design of NHTSA and EPA's standards; (2) how they are collaborating to set these standards; (3) improvements compared to a previous rulemaking NHTSA made to the modeling; and (4) the extent to which NHTSA analyzed the effects of past light truck standards and the accuracy of data used to set them.

Available in PDF, EPUB and Kindle. Book excerpt: The last ten years have seen explosive growth in the technology available to the collision analyst, changing the way reconstruction is practiced in fundamental ways. The greatest technological advances for the crash reconstruction community have come in the realms of photogrammetry and digital media analysis. The widespread use of scanning technology has facilitated the implementation of powerful new tools to digitize forensic data, create 3D models and visualize and analyze crash vehicles and environments. The introduction of unmanned aerial systems and standardization of crash data recorders to the crash reconstruction community have enhanced the ability of a crash analyst to visualize and model the components of a crash reconstruction. Because of the technological changes occurring in the industry, many SAE papers have been written to address the validation and use of new tools for collision reconstruction. Collision Reconstruction Methodologies Volumes 1-12 bring together seminal SAE technical papers surrounding advancements in the crash reconstruction field. Topics featured in the series include: • Night Vision Study and Photogrammetry • Vehicle Event Data Recorders • Motorcycle, Heavy Vehicle, Bicycle and Pedestrian Accident Reconstruction The goal is to provide the latest technologies and methodologies being introduced into collision reconstruction - appealing to crash analysts, consultants and safety engineers alike.

Wood and published by Smithers Rapra Technology. This book was released on 2009-01 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to provide guidelines to generate tensile strain rate test data for ferrous and non-ferrous sheet metals for use in finite element based automotive crash simulation tools. Specifically, measurement of the strength hardening in a sheet material resulting from strain rate testing using a high speed servo hydraulic test machine. Additionally, to provide guidelines to process raw test data, fit material model and format this data for application in crash simulation tools. It is not within the scope of these recommendations to advocate a material model to fit to strain rate test results, although useful models are referenced. Rather to give guidance on the error allowance in fitting model to test results. These guidelines are expected to have broader application in the transport industry sector.

This book was released on 2012-12-06 with total page 624 pages. Available in PDF, EPUB and Kindle. Book excerpt: A systematic treatment of current crashworthiness practice in the automotive, railroad and aircraft industries. Structural, exterior and interior design, occupant biomechanics, seat and restraint systems are dealt with, taking account of statistical data, current regulations and state-of-the-art design tool capabilities. Occupant kinematics and biomechanics are reviewed, leading to a basic understanding of human tolerance to impact and of the use of anthropometric test dummies and mathematical modelling techniques. Different types of restraining systems are described in terms of impact biomechanics. The material and structural behaviour of vehicle components is discussed in relation to crash testing. A variety of commonly used techniques for simulating occupants and structures are presented, in particular the use of multibody dynamics, finite element methods and simplified macro-elements, in the context of design tools of increasing complexity, which can be used to model both vehicles and occupants. Audience: An excellent reference for researchers, engineers, students and all other professionals involved in crashworthiness work.
