This book presents a unified approach to fracture behavior of natural and synthetic fiber-reinforced polymer composites on the basis of fiber orientation, the addition of fillers, characterization, properties and applications. In addition, the book contains an extensive survey of recent improvements in the research and development of fracture analysis of FRP composites that are used to make higher fracture toughness composites in various applications.The FRP composites are an emerging area in polymer science with many structural applications. The rise in materials failure by fracture has forced scientists and researchers to develop new higher strength materials for obtaining higher fracture toughness. Therefore, further knowledge and insight into the different modes of fracture behavior of FRP composites are critical to expanding the range of their application.

The growing use of polymer composites is leading to increasing demand for fractographic expertise. Fractography is the study of fracture surface morphologies and it gives an insight into damage and failure mechanisms, underpinning the development of physically-based failure criteria. In composites research it provides a crucial link between predictive models and experimental observations. Finally, it is vital for post-mortem analysis of failed or crashed polymer composite components, the findings of which can be used to optimise future designs.Failure analysis and fractography of polymer composites covers the following topics: methodology and tools for failure analysis; fibre-dominated failures; delamination-dominated failures; fatigue failures; the influence of fibre architecture on failure; types of defect and damage; case studies of failures due to overload and design deficiencies; case studies of failures due to material and manufacturing defects; and case studies of failures due to in-service factors.With its distinguished author, Failure analysis and fractography of polymer composites is a standard reference text for researchers working on damage and failure mechanisms in composites, engineers characterising manufacturing and in-service defects in composite structures, and investigators undertaking post-mortem failure analysis of components. The book is aimed at both academic and industrial users, specifically final year and postgraduate engineering and materials students researching composites and industry designers and engineers in aerospace, civil, marine, power and transport applications. - Examines the study of fracture surface morphologies in uderstanding composite structural behaviour - Discusses composites research and post-modern analysis of failed or crashed polymer composite components - Provides an overview of damage mechanisms, types of defect and failure criteria

Composites are now extensively used in applications where outstanding mechanical properties are necessary in combination with weight savings, due to their highly tunable microstructure and mechanical properties. These properties present great potential for part integration, which results in lower manufacturing costs and faster time to market. Composites also have a high level of styling flexibility in terms of deep drawn panel, which goes beyond what can be achieved with metal stampings. The so-called multifunctional or smart composites provide significant benefits to the vehicles as compared to the traditional materials that only have monotonic properties. CAE Design and Failure Analysis of Automotive Composites focuses on the latest use of CAE (Computer-Aided Engineering) methods in design and failure analysis of composite materials and structures, beginning with a brief introduction to the design and failure analysis of composite materials, and then presenting some recent, innovative CAE design examples of composite structures by engineers from major CAE developers and automobile OEMs and suppliers. This title brings together 12 SAE technical papers, carefully selected by the editors covering three main areas of expertise: • Design and Failure Analysis of Composites: Static Loading • Design and Failure Analysis of Composites: Dynamic and Impact Loading • Design and Failure Analysis of Composites: Blast Loading

Written by Puck's pupil and appointed successor Martin Knops, this book presents Alfred Puck ́s failure model, which, among several other theories, predicts fracture limits best and describes the failure phenomena in FRP most realistically – as confirmed within the "World-wide Failure Exercise". Using Puck ́s model the composite engineer can follow the gradual failure process in a laminate and deduce from the results of the analysis how to improve the laminate design.

Failure Analysis in 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. The book describes a broad range of techniques and strategies for the compositional and failure analysis of polymeric materials and products. It also illustrates the application of analytical methods for solving commonly encountered problems. Topics of interest include failure analysis, mechanical and physical properties, structural health monitoring, durability and life prediction, modelling of damage processes of natural fiber, synthetic fibers, and more. 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

In contrast to metals, a composite material acquires an internal structure where the imprint of its manufacturing process history is a significant part of the internal structure's makeup and in many cases determines how the material responds to external impulses. The performance for which a composite material is designed must therefore be assessed with due consideration to the manufacturing-induced features in the material volume. Failure theories based on homogenized composites cannot deliver reliable methodologies for performance assessment. This book details approaches that depart from traditional treatments by accounting for manufacturing defects in composite materials. It discusses how manufacturing defects are produced and how they affect the performance of composite materials. Serves as the only book to bring knowledge on manufacturing and failure modeling together in a coherent manner. Guides readers on mechanisms-based modeling with a focus on defects. Treats statistical simulation of microstructure with defects aimed at physical modeling. Covers manufacturing methods for polymer matrix composites. Describes failure modes in unidirectional composites and laminates in the presence of defects. Discusses fatigue damage in the presence of defects. This book is aimed at researchers in industry and academia in aerospace engineering, mechanical engineering, and materials science and engineering. It also serves as a reference for students taking advanced courses in composite materials.

This book covers recent advancement methods used in analysing the root cause of engineering failures and the proactive suggestion for future failure prevention. The techniques used especially non-destructive testing such X-ray are well described. The failure analysis covers materials for metal and composites for various applications in mechanical, civil and electrical applications. The modes of failures that are well explained include fracture, fatigue, corrosion and high-temperature failure mechanisms. The administrative part of failures is also presented in the chapter of failure rate analysis. The book will bring you on a tour on how to apply mechanical, electrical and civil engineering fundamental concepts and to understand the prediction of root cause of failures. The topics explained comprehensively the reliable test that one should perform in order to investigate the cause of machines, component or material failures at the macroscopic and microscopic level. I hope the material is not too theoretical and you find the case study, the analysis will assist you in tackling your own failure investigation case.
