The approach consists of two steps: (1) elastic–plastic finite Received in revised form 9 June 2008 element (FE) analysis of the component; and, (2) the application of a multiaxial fatigue cri- terion for the crack initiation and growth predictions based on the outputted stress–strain response from the FE analysis. The FE analysis is characterized by the implementation of an advanced cyclic plasticity theory that captures the important cyclic plasticity behavior of Keywords: the material under the general loading conditions. The fatigue approach is based upon Damage accumulation the notion that a material point fails when the accumulated fatigue damage reaches a cer- Fatigue crack growth Fatigue criterion tain value and the rule is applicable for both crack initiation and growth. As a result, one s
