Book Description
One of the oldest and most firmly established concepts associated with the fracture of uniform homogeneous materials is the idea that strain energy release rate can be used to characterize the "driving force" for flaw growth, that is, the tendency for propagation. For linear elastic treatments of self-similar crack propagation the concept can be shown to be equivalent to the single parameter field stress intensity representation. The inhomogeneity and nonuniformity of composite materials and the consequent complexity of damage makes a direct extension of that concept to damage development in those materials difficult, if not impossible. Progress in that direction has been hampered by difficulty in defining the stress state in a damaged composite, and by inadequate laboratory information concerning the precise physical nature of the damage state.

Book Description
This standardization handbook has been developed and is being maintained as a joint effort of the Department of Defense and the Federal Aviation Administration. It provides guidelines and material properties for polymer (organic) and metal matrix composite materials. This handbook aims to provide a standard source of statistically-based mechanical property data, procedures, and overall materials guidelines for characterization of composite material systems. This volume provides methodologies and lessons learned for the design, manufacture, and analysis of composite structures and for utilization of the material data provided in Volume II consistent with the guidance provided in Volume I. It covers processes and effects of variability; quality control of production materials; design and analysis; structural behavior of joints and reliability; thick section composites; and supportability.

Book Description
New developments in the applications of fracture mechanics to engineering problems have taken place in the last years. Composite materials have extensively been used in engineering problems. Quasi-brittle materials including concrete, cement pastes, rock, soil, etc. all benefit from these developments. Layered materials and especially thin film/substrate systems are becoming important in small volume systems used in micro and nanoelectromechancial systems (MEMS and NEMS). Nanostructured materials are being introduced in our every day life. In all these problems fracture mechanics plays a major role for the prediction of failure and safe design of materials and structures. These new challenges motivated the author to proceed with the second edition of the book. The second edition of the book contains four new chapters in addition to the ten chapters of the first edition. The fourteen chapters of the book cover the basic principles and traditional applications, as well as the latest developments of fracture mechanics as applied to problems of composite materials, thin films, nanoindentation and cementitious materials. Thus the book provides an introductory coverage of the traditional and contemporary applications of fracture mechanics in problems of utmost technological importance. With the addition of the four new chapters the book presents a comprehensive treatment of fracture mechanics. It includes the basic principles and traditional applications as well as the new frontiers of research of fracture mechanics during the last three decades in topics of contemporary importance, like composites, thin films, nanoindentation and cementitious materials. The book contains fifty example problems and more than two hundred unsolved problems. A "Solutions Manual" is available upon request for course instructors from the author.
