This book covers the fatigue testing of specimens, curve fitting of equations to the test data, and the use of such equations in life prediction. Earlier chapters are background in the nature of rubber, history of its usage, brief mention of types of rubber and manufacturing methods. Stress-strain testing and behavior is covered to the extent relevant to fatigue analysis. Also, the text covers the application of finite element analysis to components to determine high stress points that are vulnerable to fatigue failure. It is a very useful reference for practicing engineers charged with the responsibility to design structural rubber components where fatigue life is a concern. It also serves as a text for short courses, or as a supplementary text for a university course in rubber engineering.
