Creep and Fatigue in Polymer Matrix Composites, Second Edition, updates the latest research in modeling and predicting creep and fatigue in polymer matrix composites. The first part of the book reviews the modeling of viscoelastic and viscoplastic behavior as a way of predicting performance and service life. Final sections discuss techniques for modeling creep rupture and failure and how to test and predict long-term creep and fatigue in polymer matrix composites. - Reviews the latest research in modeling and predicting creep and fatigue in polymer matrix composites - Puts a specific focus on viscoelastic and viscoplastic modeling - Features the time-temperature-age superposition principle for predicting long-term response - Examines the creep rupture and damage interaction, with a particular focus on time-dependent failure criteria for the lifetime prediction of polymer matrix composite structures that are illustrated using experimental cases
Load-Bearing Fibre Composites provides a unified view of the entire field of fiber and platelet composites. This book explores the complex interactions between fibers and matrix. Organized into 12 chapters, this book begins with an overview of the fundamental ideas in the field of fiber reinforced composites. This text then provides data on their load-bearing capabilities. Other chapters consider a rough estimate of how strong a material could be and describe the two main sources of weakness in real materials. This book discusses as well the slender forms of material and describes the simple slip theory of reinforcement that gives the modulus and strength for aligned short-fiber composites. The final chapter deals with the versatile use of fiber reinforced materials, which can be designed for a specific application by suitable choice of components and volume fraction. This book is a valuable resource for materials scientists, metallurgists, designers, engineers, and research workers.
Mechanical and Physical Testing of Biocomposites, Fibre-Reinforced Composites and Hybrid Composites covers key aspects of fracture and failure in natural/synthetic fiber reinforced polymer based composite materials, ranging from crack propagation, to crack growth, and from notch-size effect, to damage-tolerant design. Topics of interest include mechanical properties, such as tensile, flexural, compression, shear, impact, fracture toughness, low and high velocity impact, and anti-ballistic properties of natural fiber, synthetic fibers and hybrid composites materials. It also covers physical properties, such as density, water absorption, thickness swelling, and void content of composite materials fabricated from natural or synthetic materials. Written by leading experts in the field, and covering composite materials developed from different natural fibers and their hybridization with synthetic fibers, the book's chapters provide cutting-edge, up-to-date research on the characterization, analysis and modelling of composite materials. - Contains contributions from leading experts in the field - Discusses recent progress on failure analysis, SHM, durability, life prediction and the modelling of damage in natural fiber-based composite materials - Covers experimental, analytical and numerical analysis - Provides detailed and comprehensive information on mechanical properties, testing methods and modelling techniques
This volume contains the edited version of lectures and selected research contributions presented at the NATO ADVANCED STUDY INSTITUTE on ADVANCES IN FATIGUE SCIENCE AND TECHNOLOGY. held in Alvor. Portugal, 4th to 15th of April 1988. and organized by CEMUL - Center of Mechanics and Materials of The Technical University of Lisbon. The Institute was attended by 101 participants, including 15 lecturers. from 14 countries. The participants were leading scientists and engineers from universities, research institutions and industry. and also Ph.D~ students. Some participants presented papers during the Institute reporting the state-of-art of their research projects. All the sessions wel'e very active and quite extensive discussions on scientific aspects took place during the Institute. The Advanced Study Institute provided a forum for interaction among eminent scientists and engineers. from different schools of thought and young researchers. The Institute addressed the foundations and current state of the art of essential aspects related to fatigue science and technology, namely: Short Cracks, Metallurgical Aspects, Environmental Fatigue, Threshold Behaviour, Notch Behaviour. Creep and Fatigue Interactions at High Temperature, Multiaxial Fatigue, Low Cycle Fatigue, Methodology of Fatigue Testing, Variable Amplitude Fatigue, Fatigue of Advanced Materials. Elastic-Plastic Fatigue, and several engineering applications such as welded joints, energy systems, offshore structures, automotive industry, machine and engine components. This book is organized in three parts: Part I: Fundamentals of Fatigue Part II: Engineering Applications Part III: Research Contributions The research contributions covered most of the areas referred above.
Having fully established themselves as workable engineering materials, composite materials are now increasingly commonplace around the world. Serves as both a text and reference guide to the behavior of composite materials in different engineering applications. Revised for this Second Edition, the text includes a general discussion of composites as material, practical aspects of design and performance, and further analysis that will be helpful to those engaged in research on composites. Each chapter closes with references for further reading and a set of problems that will be useful in developing a better understanding of the subject.
Fatigue Life Prediction of Composites and Composite Structures, Second Edition, is a comprehensive review of fatigue damage and fatigue life modeling and prediction methodologies for composites and their use in practice. In this new edition, existing chapters are fully updated, while new chapters are introduced to cover the most recent developments in the field. The use of composites is growing in structural applications in many industries, including aerospace, marine, wind turbine and civil engineering. However, there are uncertainties about their long-term performance, including performance issues relating to cyclic fatigue loading that hinder the adoption of a commonly accepted credible fatigue design methodology for the life prediction of composite engineering structures. With its distinguished editor and international team of contributors, this book is a standard reference for industry professionals and researchers alike. - Examines past, present and future trends associated with the fatigue life prediction of composite materials and structures - Assesses novel computational methods for fatigue life modeling and prediction of composite materials under constant amplitude loading - Covers a wide range of techniques for predicting fatigue, including their theoretical background and practical applications - Addresses new topics and covers contemporary research developments in the field
