Abstract:  
A cumulative fatigue damage precedure that considers notch effects, mean stress relaxation and cyclic hardening and softening is being used at TEREX to evaluate structural reliability. Necessary inputs for the evaluation are: 1) a load time history of the response of the material to its operating enviroment, 2) a listing of material characteristics with regard to both monotonic and cyclic properties, 3) an experimental sample with similar section which can be failed under constant amplitude loading so that a fatigue concentration factor can be developed and 4) the appropriate computer soft ware needed to simulate the material during its loading enviroment so that a life prediction can be made.
