A Study on the Multiaxial Fatigue Failure Criterion with Small Defects



This paper reexamines a multiaxial fatigue failure criterion in the presence of small defects. The criterion is based on the assumption that a Mode-I crack on a specified plane, termed a critical plane, plays a dominant role in the determination of fatigue strength. The present study extends previous research to propose a modified failure criterion in conjunction with a systematic computational scheme, and to conduct a detailed analysis of its predictive capability. Using the proposed computational scheme, the applied stress level for the multiaxial fatigue failure can be efficiently predicted for both in-phase and out-of-phase loadings. Additionally, a series of parametric studies was conducted to examine the material's sensitivity to the biaxial stress state with respect to the fatigue strength.
