Download or read book Failure Analysis and Fractography of Polymer Composites written by Emile Greenhalgh and published by Elsevier. This book was released on 2009-09-28 with total page 608 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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

Download or read book The Compressive Behavior of Glass Fiber Reinforced Composites Subjected to Local Thermal Loading written by Catherine Meaghan Westover and published by . This book was released on 2000 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental study has been conducted to determine the effects of local thermal loading on the compressive behavior of glass fiber composites. The primary factors considered were the intensity of thermal loading and the applied compressive load. The material specimens tested were laminate plates composed of Micarta 010 FR4, a fire retardant glass/epoxy laminate. Two types of testing were conducted for heat fluxes of 85 kW/m2, 140 kW/m2, and 195 kW/m2. The first type involved the unloaded radiant thermal testing of the material and provided a baseline from which the effects of thermal loading on the physical properties of the composite specimen were determined. The second type was a combined loading test, which involved loading specimens in compression to a constant applied load and subjecting them to a local thermal load.

Download or read book Multi scale Modelling of Compressive Behaviour of Materials with Pronounced Internal Microstructure written by Bartlomiej Winiarski and published by . This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: All composite constituents are modelled as linear-elastic material, where both isotropic and anisotropic materials are considered depending on the length-scale. It is assumed that the moment of stability loss in the microstructure of materials is treated as the onset of the fracture process. Besides that, the critical strain that corresponds to loss of stability in the microstructure of the composite, either surface or internal instability, must be smaller than the critical strain that corresponds to loss of stability of the entire composite. This project involves parameterised variables, such as the crack size, the crack spacing, the layer volume fraction and the fibre volume fraction. At each length-scale two types of cracks are analysed, namely, cracks with stress-free crack faces and cracks with frictionless Hertzian contact of the crack faces. A number of finite-element models for each length-scale are developed, and are validated analytically and numerically. The models' ability to simulate practical composite structures to a useful degree of accuracy with suitable material properties is discussed. A number of parameters, which quantifies the interfacial crack interaction and crack faces contact interaction phenomena, are introduced and discussed. Qualitative discussion on the crack faces contact zones, post-critical behaviour of composites and crack propagation are presented and discussed. Finally, the subject areas for the future work are outlined.

Available in PDF, EPUB and Kindle. Book excerpt: Cement-Based Composites takes a different approach from most other books in the field by viewing concrete as an advanced composite material, and by considering the properties and behaviour of cement-based materials from this stance. It deals particularly, but not exclusively, with newer forms of cement-based materials. This new edition takes a critical approach to the subject as well as presenting up-to-date knowledge. Emphasis is given to non-conventional reinforcement and design methods, problems at the materials' interfaces and to the durability of structures. High strength composites and novel forms of cement-based composites are described in detail. After a basic introduction the book explores the various components of these materials and their properties. It then deals with mechanical properties and considers characteristics under various loading and environmental conditions, and concludes by examining design, optimization and economics with particular emphasis on high-performance concretes. Researchers, graduate students and practising engineers will find this book valuable.

Download or read book High Temperature Mechanical Behaviour of Ceramic Composites written by Karl Jakus and published by Elsevier. This book was released on 1995-06-28 with total page 569 pages. Available in PDF, EPUB and Kindle. Book excerpt: High Temperature Mechanical Behavior of Ceramic Composites provides an up-to-date comprehensive coverage of the mechanical behavior of ceramic matrix composites at elevated temperatures. Topics include both short-term behavior (strength, fracture toughness and R-curve behavior) and long-term behavior (creep, creep-fatigue, delayed failure and lifetime). Emphasis is on a review of fundamentals and on the mechanics and mechanisms underlying properties. This is the first time that complete information of elevated temperature behavior of ceramic composites has ever been compacted together in a single volume. Of particular importance is that each chapter, written by internationally recognized experts, includes a substantial review component enabling the new material to be put in proper perspective.

Download or read book Analysis of Compressive Behaviour in Fibre Direction of Laminated Composite Structures in Presence of Matrix Degradation and Stress Concentrations written by Aldo Cocchi and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Determination of compressive properties at failure is an important factor for the design of composite structures. In this work, an analysis concerning the compression strength in fibre direction of composite structures is presented. A novel specimen geometry is proposed with the aim to obtain failure in a valid zone of the coupon free of stress concentrations. Experimental tests permitted to validate the usage of the new coupon in compression and four-points bending, at room and elevated temperature. Further tests permitted to study the influence of matrix degradation on compressive strength in fibre direction. Experimental results demonstrated different behaviours for carbon and glass reinforced plastics. A non-local failure criterion was utilized to predict the strength of composite structures with stress concentrations in tension and compression. The identified parameters were validated on coupons presenting size effects. The failure mechanisms of particular laminates in static and fatigue tension (ex. quasi-isotropic) where analyzed. Delamination can be the cause of these failures, in particular for UD plies and brittle matrices. In other cases, failure can be explained by compression failure in fibre direction generated by Poisson effect and favoured by matrix degradation. This failure mechanism permitted to model the experimental results in fatigue loading for quasi-isotropic laminates fabricated with a balanced carbon/PEEK woven ply. Finally the influence of matrix damage on the characteristic length of the non-local failure criterion was assessed on pre-damaged coupons with stress concentrations.
