This book was released on 1991 with total page 764 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last 25 years, the science and technology of composite materials have experienced a period of substantial development. Composite materials have been introduced, or are expected to serve, in many functions which cannot be fulfilled by conventional materials, particularly in extreme environments. The research focus has been broadened to include not only new polymer system, but also metal matrix composites, intermetallic compounds and ceramic materials. This has brought forth a number of new problems in fabrication and processing, and in analysis of composite material behavior and properties. The latter set of problems is usually approached by various micromechanical techniques. In recent years, their scope has been expanded from prediction of overall properties of elastic, perfectly bonded systems, to include problems associated with inelastic deformation of the phases, debonding at interfaces, and growth of distributed damage. Many familiar aspects of mechanical behavior, such as fracture, fatigue, compressive strength and buckling have been reexamined and adapted for application to the new material systems.

Book excerpt: Under these circumstances, it fs essential to develop micromechanical theories which evaluate the local fields and predict the overall response under combined thermal and mechanical loads. The basic elements of these theories are geometrical modeling of the microstructures and local interactions, and constitutive modeling of the homogeneous phases. An essential requirement of the latter is to include inelastic deformation to model composite systems which exhibit nonlinear response under thermal and mechanical service loads. Since the early 1960s, micromechanics of composite materials has attracted many researchers. This led to significant theoretical developments for prediction of elastic and inelastic constitutive response, and motivated experimental validation. The purpose is to summarize these developments, and illustrate their application in predicting the overall response under thermomechanical loads. Although treatment of the subject in this chapter covers two-phase particulate and fibrous materials, the focus in applications will be on fibrous composites and laminates.

This book was released on 2012-12-09 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a broad exposition of analytical and numerical methods for modeling composite materials, laminates, polycrystals and other heterogeneous solids, with emphasis on connections between material properties and responses on several length scales, ranging from the nano and microscales to the macroscale. Many new results and methods developed by the author are incorporated into the rich fabric of the subject, which has developed from the work of many researchers over the last 50 years. Among the new results, the book offers an extensive analysis of internal and interface stresses caused by eigenstrains, such as thermal, transformation and inelastic strains in the constituents, which often exceed those caused by mechanical loads, and of inelastic behavior of metal matrix composites. Fiber prestress in laminates, and modeling of functionally graded materials are also analyzed. Furthermore, this book outlines several key subjects on modeling the properties of composites reinforced by particles of various shapes, aligned fibers, symmetric laminated plates and metal matrix composites. This volume is intended for advanced undergraduate and graduate students, researchers and engineers interested and involved in analysis and design of composite structures.

Available in PDF, EPUB and Kindle. Book excerpt: Themethodologyfordesigninghigh-performancecompositestructuresisstill evo- ing. The complexity of the response of composite materials and the dif?culties in predicting the composite material properties from the basic properties of the c- stituents result in the need for a well-planned and exhaustive test program. The recommended practice to mitigate the technological risks associated with advanced composite materials is to substantiate the performance and durability of the design in a sequence of steps known as the Building Block Approach. The Building Block Approach ensures that cost and performance objectives are met by testing greater numbers of smaller, less expensive specimens. In this way, technology risks are assessed early in the program. In addition, the knowledge acquired at a given level of structural complexity is built up before progressing to a level of increased complexity. Achieving substantiation of structural performance by testing alone can be p- hibitively expensive because of the number of specimens and components required to characterize all material systems, loading scenarios and boundary conditions. Building Block Approachprogramscan achieve signi?cant cost reductionsby se- ing a synergy between testing and analysis. The more the development relies on analysis, the less expensive it becomes. The use of advanced computational models for the prediction of the mechanical response of composite structures can replace some of the mechanical tests and can signi?cantly reduce the cost of designing with composites while providing to the engineers the information necessary to achieve an optimized design.

Available in PDF, EPUB and Kindle. Book excerpt: This book contains fifteen papers based on the presentations made at the symposium on "Inelasticity and Micromechanics of Metal Matrix Composites" held at the University of Washington, USA, in mid-1994. The papers represent the most recent work conducted on inelasticity and micromechanics of metal matrix composites. The book is divided into two parts: Part I deals with the study of inelastic deformation in metal matrix composites, while Part II tackles the micromechanical aspects of metal matrix composites. The articles discuss different aspects of these two topics ranging from purely theoretical treatments to extensive experimental investigations. Many of the papers are by prominent researchers working in this area.

Book excerpt: The inelastic deformation mechanisms for the SiC (SCS-6)/Ti-15-3 system were studied at 538 C (1000 F) using a combination of mechanical measurements and detailed microstructural examinations. The objectives were to evaluate the contributions of plasticity and damage to the overall MMC response, and to compare the room temperature and elevated temperature deformation behaviors. Four different laminates were studied: (0)8, (90)8, (] or -45)2s, and (0/90)2s, with the primary emphasis on the unidirectional (0)8, and (90)8 systems. The elevated temperature responses were similar to those at room temperature, involving a two-stage elastic-plastic type of response for the (0)8 system, and a characteristic three-stage deformation response for the (90)8 and (+ or -45)2s systems. The primary effects of elevated temperatures included: (1) reduction in the 'yield' and failure strengths; (2) plasticity through diffused slip rather than concentrated planar slip (which occurred at room temperature); and (3) time-dependent deformation. The inelastic deformation mechanism for the (0)8 MMC was dominated by plasticity at both temperatures. For the (90)8 and (+ or -45)2s MMCs, a combination of damage and plasticity contributed to the deformation at both temperatures. Majumdar, B. S. and Newaz, G. M. Unspecified Center..

This book was released on 2000 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Off-axis tension (OAT) tests and biaxially loaded cruciform-shaped specimen (BC) tests on unidirectional fiber-reinforced metal matrix composites are subjected to detailed analyses using a newly developed model. The results indicate that the off-axis tension test is a viable method for biaxial stress-strain characterization of composites in the nonlinear deformation range. It is found that, besides being much more expensive to conduct, the specific cruciform-shaped specimen test considered in the study is less amenable to unambiguous interpretation.
