Deformation Based Fatigue Damage Accumulation Model

Abstract:

This paper reports results of fatigue testing performed under fully reversible, load controlled uniaxial tension-compression. For this scheme of loading definition of relative damage indicator and cumulative damage indicator parameter was given and changes of such parameters during the life of the material were shown for two grades of steel. Simple damage criterion proposed by Johnson [6] was modified to define damage indicator parameter. Definitions of damage parameters based on proposed damage indicator and damage indicator parameter were also given. Damage curves showing changes of damage parameter as the function of the life fraction were shown to illustrate progress of damage during the life of the material.
