On the use of uniaxial one-parameter damage laws for estimating fatigue life under multiaxial loading
Abstract
The goal of this paper is to evaluate the capabilities of different one-parameter fatigue laws to estimate crack initiation in notched components under multiaxial loading. Fatigue damage is accounted for through stress-based, strain-based, and energy-based approaches while the cyclic plasticity at the notch-controlled process zone is estimated using linear-elastic simulations. The results show that energy-based formulations established from both the absorbed energy at the mid-life cycle and the energy absorbed throughout the entire life are more accurate.
