Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the present paper is to characterize static and dynamic mechanical properties of high-hardness laminar composite steel. Tensile, compressive, and shear properties were obtained. Fatigue properties were also investigated including the effect of minimum: maximum stress (R) ratio, humidity, and surface condition. Improving the as-received surface led to increased values of the fatigue limit. Fatigue resistance was lowered markedly by humidity. For a given value of maximum stress increasing the R ratio increased the number of cycles to failure. Orientation had a pronounced effect on the toughness of cracked and uncracked Charpy specimens, that is, RW orientation exhibited greater toughness than did WR. There is some evidence to indicate that constraint has caused the hard-soft interfacial bond to delaminate. Lastly, examination of the fracture surfaces of the tensile, fatigue, and Charpy specimens revealed that in most instances crack initiation phase of fracture takes place on the hard side of the composite.

Available in PDF, EPUB and Kindle. Book excerpt: Composite Materials, Volume 5: Fracture and Fatigue covers the concepts, theories, and experiments on fracture and fatigue behavior of composite materials. The book discusses the fracture of particulate composites, including metal, polymer, and ceramic matrices; relates micromechanics effects to composite strength; and summarizes the various theories relating constituent properties and microstructure to fracture. The text also describes differing theories regarding the strength and fracture of composites; and the theory and experiment relating to time-dependent fracture covering both long-term as well as dynamic fracture. The fatigue of both polymer- and metal-matrix composites and the factors influencing the toughness of both brittle and ductile matrix composites are also considered. Design engineers, materials scientist, materials engineers, and metallurgists will find the book useful.

This book was released on 1976 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study both corrosion fatigue and stress-corrosion cracking behavior of a high-hardness laminar composite steel are examined in the presence of a 3.5 percent sodium chloride (NaCl) environment and compared to the behavior in air. It is shown that the susceptibility is not limited to specimens with a crack or notch. Smooth specimens with a machine ground surface tested under static as well as cyclic loading are affected adversely by the 3.5 percent NaCl environment. Using center notched panels to study crack growth behavior, it is shown that the influence of the 3.5 percent environment becomes more apparent as the maximum cyclic stress decreases. Ballistically damaged panels were also examined in a corrosive environment under the same cyclic stress conditions. Compared to the center notched panels a longer life is observed. It is suggested that this is due to the orientation of the ballistically induced cracks with respect to the loading axis. Environmental effects are also seen in the static loading of ballistically damaged panels. KIscc estimates were obtained from these panels and compared to the results of conventional specimens. Both sets of results indicate significant susceptibility of the laminar composite steel to stress corrosion.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2013-10-22 with total page 747 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in Research on the Strength and Fracture of Materials: Volume 2Bs—Fatigue contains the proceedings of the Fourth International Conference on Fracture, held at the University of Waterloo, Canada, in June 1977. The papers review the state of the art with respect to fracture in a wide range of materials such as metals and alloys. This volume is comprised of 85 chapters and opens by discussing the metallographic aspects of fatigue in pearlitic structures and the dislocation diffusion mechanism of fatigue crack formation. The reader is then introduced to localized plastic deformation and fracture in slip bands during fatigue loading of age hardening aluminum alloys; the microstructure of fatigue fracture surfaces in titanium; mechanisms of liquid metal embrittlement, stress corrosion cracking, and corrosion-fatigue; and the fatigue behavior of macroscopic slag inclusions in steam turbo-generator rotor steels. A model for fatigue crack initiation in polycrystalline solids is also described. This monograph will be a useful resource for metallurgists, materials scientists, and structural and mechanical engineers.
