Advanced Theories For Deformation Damage And Failure In Materials

The book introduces advanced theories for deformation, damage, and failure in materials. The overall continuum mechanical framework was marked out and added by creep and damage mechanics of materials at elevated temperatures. The time-dependent and time-independent models of cyclic plasticity for low cycle and thermomechanical fatigue life assessment were specified in a very special manner: instead of three-dimensional statements, only one-dimensional rheological models were discussed. Anisotropic plasticity during non-proportional loading and anisotropy of yield/failure criteria is more and more important in modern applications. It is showing how the limit states of materials can be estimated. In addition, the damage and failure of composite materials demonstrate the possibility to extend continuum mechanics to continuum damage mechanics of composite materials.

The papers in this volume present basic concepts and new developments in failure and damage analysis with focus on advanced materials such as composites, laminates, sandwiches and foams, and also new metallic materials. Starting from some mathematical foundations (limit surfaces, symmetry considerations, invariants) new experimental results and their analysis are shown. Finally, new concepts for failure prediction and analysis will be introduced and discussed as well as new methods of failure and damage prediction for advanced metallic and non-metallic materials. Based on experimental results the traditional methods will be revised.

This book presents studies on the plasticity, failure, and damage behavior of materials and structures under monotonic and cyclic loads. Featuring contributions by leading authors from around the globe, it focuses on the description of new effects observed in experiments, such as damage under cyclic loading. It also proposes various simulation models based on different approaches and compares them with tests, taking scaling aspects into account.

This book is devoted to the deformation and failure in metallic materials, summarizing the results of a research programme financed by the "Deutsche Forschungsgemeinschaft". It presents the recent engineering as well as mathematical key aspects of this field for a broad community. Its main focus is on the constitutive behaviour as well as the damage and fracture of metallic materials, covering their mathematical foundation, modelling and numerics, but also relevant experiments and their verification.

This book presents current trends in Mechanics of Time Dependent Materials. It covers a number of cutting-edge themes, such as characterization of linear and nonlinear mechanical behavior of viscoelastic materials and their composites, taking into consideration large deformations, low, moderate and large strain rates, as well as failure and fracture phenomena. The contributions are inspired by advanced applications in modern technologies, such as injection molding and extrusion.

Fundamentals of Machine Component Design bridges theory and practice to provide readers with a thorough understanding of best practices for machine component design and application. Load and stress analysis, fatigue, fracture, and other mechanical behaviors that can result in the failure of a machine component are discussed in the early chapters, before the book moves onto to cover different connections (welded and bolted) prevalent in machine components, and then individual components such as gears, shafts, bearings, springs, pressure vessels, brakes, clutches, keys and couplings, and more. The book ends with chapters outlining different design methods as well as design problems for readers to practice with, the solutions to which are also provided. Covers the design of shafts, power screws, bolts, welded connections, springs, and pressure vessels, as well as transmitted power elements such as belts, chains, gears, and wire ropes Outlines finite element methods and other techniques that can be used for effectively designing machine components Discusses contact and sliding bearings, keys and couplings, gears (helical, spur, bevel, and worm), and more Includes solved problems to help readers refine their skills

This book provides in a single and unified volume a clear and thorough presentation of the recent advances in continuum damage mechanics for metals and metal matrix composites. Emphasis is placed on the theoretical formulation of the different constitutive models in this area, but sections are added to demonstrate the applications of the theory. In addition, some sections contain new material that has not appeared before in the literature. The book is divided into three major parts: Part I deals with the scalar formulation and is limited to the analysis of isotropic damage in materials; Parts II and III deal with the tensor formulation and is applied to general states of deformation and damage. The material appearing in this text is limited to plastic deformation and damage in ductile materials (e.g. metals and metal matrix composites) but excludes many of the recent advances made in creep, brittle fracture, and temperature effects since the authors feel that these topics require a separate volume for this presentation. Furthermore, the applications presented in this book are the simplest possible ones and are mainly based on the uniaxial tension test.

This book provides an overview of the failure of materials - everything from metals to brittle ceramics.
