Abstract:
A method of determining material constants of a hardened metal object being exerted to load cycles, and a method of indicating fatigue damage rate of a hardened metal object in relation to load cycles, N, exerted on the hardened metal object, wherein material dependent constants of the hardened metal object are determined according to the method of determining material dependent constants of the hardened metal object. Methods for indicating fatigue and predicting life of a metal object are disclosed.
