Evolution of Fatigue Design and Evaluation Technologies

Activities within the Society of Automotive Engineers originating circa 1966 in Division 4 of the Iron and Steel Technical Committee Said the foundation for the contemporary approach to cumulative fatigue damage analysis and component lifetime predictive techniques. Previous and current activities of the Division 4 successor, the Fatigue Design and Evaluation Committee, have established the local stress-strain approach to ground vehicle durability as the industry-accepted methodology for fatigue design of critical components and structures subject to cyclic loading. This paper outlines the chronology of significant events and individuals within the Society of Automotive Engineers fatigue community that have advanced our comprehension, and offered solutions to the rather complex problem of durability by design.
