This monograph presents numerical methods for solving transient wave equations (i.e. in time domain). More precisely, it provides an overview of continuous and discontinuous finite element methods for these equations, including their implementation in physical models, an extensive description of 2D and 3D elements with different shapes, such as prisms or pyramids, an analysis of the accuracy of the methods and the study of the Maxwell’s system and the important problem of its spurious free approximations. After recalling the classical models, i.e. acoustics, linear elastodynamics and electromagnetism and their variational formulations, the authors present a wide variety of finite elements of different shapes useful for the numerical resolution of wave equations. Then, they focus on the construction of efficient continuous and discontinuous Galerkin methods and study their accuracy by plane wave techniques and a priori error estimates. A chapter is devoted to the Maxwell’s system and the important problem of its spurious-free approximations. Treatment of unbounded domains by Absorbing Boundary Conditions (ABC) and Perfectly Matched Layers (PML) is described and analyzed in a separate chapter. The two last chapters deal with time approximation including local time-stepping and with the study of some complex models, i.e. acoustics in flow, gravity waves and vibrating thin plates. Throughout, emphasis is put on the accuracy and computational efficiency of the methods, with attention brought to their practical aspects.
This monograph also covers in details the theoretical foundations and numerical analysis of these methods. As a result, this monograph will be of interest to practitioners, researchers, engineers and graduate students involved in the numerical simulation

Описание: This book is based on the findings, issues and questions related to an ongoing decade-old research project named the Innovation Lab (www.innovation-lab.org). The research project focuses on discontinuous innovation in more than thirteen countries, most of which are European, and provides useful insights into its different challenges. It also raises several questions related to the subject, some of which are: how do firms pick up weak signals on emerging -- and possibly radically different -- innovation? What should firms do when these weak signals hit their "mainstream" process? What are the criteria for allocating resources to a strategic innovation project? What actions should firms take to avoid being left out by the "corporate immune system"? How should firms organize projects that often break existing rules and require new rules to be created?This book attempts to provide answers to the above mentioned questions by gathering information from the research project and also from firms that have tried exploring various ideas, models and insights to tackle discontinuous innovation. Written in a simple and accessible manner, this book will be of interest to both practitioners and academics alike.

Описание: Provides the theoretical and practical background to design and use discontinuous fiber-reinforced polymer materials, with an emphasis on structural parts for the automotive industry. Moreover, the product of years of collaborative work between industry and academia is presented in an easy-to-use, comprehensive manner.
Описание: Discontinuous long fiber-reinforced polymer structures with local continuous fiber reinforcements represent an important class of lightweight materials with broad design possibilities and various technical applications, eg, in vehicle construction. However, in contrast to continuous fiber-reinforced composites, extensively used in the aircraft industry, there is still a lack of integrated and experimentally proven concepts for manufacture, modeling, and dimensioning of combinations of discontinuously and continuously reinforced polymer structures. This is partly ascribed to the complexity of the manufacturing processes of discontinuously reinforced polymers, heterogeneous, anisotropic, and nonlinear material and structural properties, but also to the resulting bonding problem of both material types.This book addresses these issues, including both continuous and discontinuous fiber processing strategies. Specific design strategies for advanced composite reinforcement are provided with an integrated and holistic approach for composites material selection, product design, and mechanical properties. Characterization, simulation, technology, design, future research, and implementation directions are also included.In the field of application of three-dimensional load-bearing structures, this book provides an excellent foundation for the enhancement of scientific methods and engineers who need an interdisciplinary understanding of process and materials techniques, as well as simulation and product development methods.
Описание: Martin Hewing and co-author Katharina Holzle explore the potential that can arise through collaboration with potential users who are not yet users. Those users at the peripheries are perceived to contribute more novel information, by which they better reflect shifts in needs and behavior than current users at the center.
