The fatigue properties of materials [electronic resource] / E.G. Eeles and R.C.A. Thurston, Physical Metallurgy Division. Ottawa : Queen's Printer, 1968. vi, 54 p. : charts, ill. Technical bulletin ; TB 97 Cover title. "March 1968." Digitized edition from print [produced by Natural Resources Canada]. Includes bibliographical references (p. 26-30). “Fatigue is the process responsible for the majority of service failures of engineering components and structures, and consequently its many ramifications have been intensively studied by physicists, metallurgists and engineers. The process consists essentially of two separate stages, crack initiation and crack propagation, which are affected differently by external variables. The mechanisms responsible for the development of these two stages, the parameters which control them, and the empirical relationships derived for the use of design engineers are discussed on the basis of the most recent available information. Attention is drawn to those areas where further fundamental or applied research is required, and some of the limitations of existing theories are mentioned. The fatigue properties of ultra-high-strength steels, aluminum alloys, titanium alloys, and composite materials (both metallic and non-metallic), are presented and discussed in terms of the foregoing review. In particular, the effects of the environment are examined in the light of the theme of the International Symposium on Materials, Key to Effective Use of the Sea, held in New York, N.Y., September 12-14, 1967"--Abstract, p. i.
