Book Description
Since metal matrix composites (MMC) are composed from two very distinct materials each having their own physical and mechanical properties, it is feasible that the fatigue resistance depends on the strength of the weaker constituent. Based on this assumption, isothermal fatigue lives of several MMC's were analyzed utilizing a fatigue life diagram approach. For each MMC, the fatigue life diagram was quantified using the mechanical properties of its constituents. The fatigue life regions controlled by fiber fracture and matrix were also quantitatively defined. Radhakrishnan, V. M. and Bartolotta, Paul A.

Book Description
This book provides the first comprehensive review of its kind on the long-term behaviour of composite materials and structures subjected to time variable mechanical, thermal, and chemical influences, a subject of critical importance to the design, development, and certification of high performance engineering structures. Specific topics examined include damage, damage characterization, and damage mechanics; fatigue testing and evaluation; fatigue behaviour of short and long fibre reinforced polymer and metal matrix materials; viscoelastic and moisture effects; delamination; statistical considerations; the modeling of cumulative damage development; and life prediction. The volume provides an extensive presentation of data, discussions, and comparisons on the behaviour of the major types of material systems in current use, as well as extensive analysis and modeling (including the first presentation of work not found elsewhere). The book will be of special interest to engineers concerned with reliability, maintainability, safety, certification, and damage tolerance; to materials developers concerned with making materials for long-term service, especially under severe loads and environments, and to lecturers, students, and researchers involved in material system design, performance, solid mechanics, fatigue, durability, and composite materials. The scope of the work extends from entry level material to the frontiers of the subject.

Book Description
An Introduction to Fatigue in Metals and Composites provides a balanced treatment of the phenomenon of fatigue in metals, nonmetals and composites with polymeric, metallic and ceramic matrices. The applicability of the safe life philosophy of design is examined for each of the materials. Attention is also focused on the stable crack growth phase of fatigue and differences in the operative mechanisms for the various classes of materials are considered. The impacts of these differences on the development of damage tolerance strategies are examined. Among topics discussed are; variable amplitude loading with tensile and compressive overload; closure obstruction; bridging mechanisms; mixed mode states; small cracks; delamination mechanisms and environmental conditions. The arrangement and presentation of the topics are such that An Introduction to Fatigue in Metals and Composites can serve as a course text for mechanical, civil, aeronautical and astronautical engineering and material science courses as well as a reference for engineers who are concerned with fatigue testing and aircraft, automobile and engine design.

Book Description
The Report is intended to update DMIC Report S-21, which describes 1967 research on fiber-reinforced metal-matrix composites. A two-page summary outlines the current state of the art of these composites, and is followed by a discussion of 1968 research on the composites, arranged according to matrix- and fiber-materials. The bulk of the report consists of summaries of 1968 research programs, arranged by programs. (Author).
