摘要：
A computational study of low-cycle fatigue behaviour of lotus-type porous material subjected to uniaxial/biaxial tension and compressive loading cycles is presented in this paper. The considered computational models have different pore topology patterns. The low-cycle fatigue analysis is performed using a damage initiation and evolution law, based on the inelastic hysteresis energy for stabilized loading cycle. The direct cyclic analysis is used to obtain the stabilized response of a model subjected to periodic loading. The present study clarifies the influences of pore topology on the low-cycle fatigue behaviour under different type of transversal loading conditions with respect to the pore orientations.
