A unifying energy approach for high cycle fatigue behavior evaluation

Abstract The purpose of this paper is to develop a unifying energy approach for rapid assessment of fatigue parameters in high-cycle fatigue regime. The energy dissipation is considered as an index of fatigue damage to analyze the progressive microstructural movements and to evaluate the fatigue behavior of low-carbon steel (e.g. residual life and microplasticity). A set of theoretical and experimental works are performed to demonstrate its applicability. The relationships between the predicted fatigue parameters and the traditional testing results are compared and discussed. It is concluded that the present approach is applicable for macro and micro high-cycle fatigue behavior evaluation.
