摘要：
The direct modelling of fatigue cracks propagation with variation in crack morphology is carried out on the base of continuum damage mechanics concept. The crack initiation and propagation is assumed to occur within the current plane of maximal damage. The various damage measures are introduced and compared for the prediction of the crack growth direction. The special measure is proposed for the description of Forsyth's Stage I crack propagation. The influence of the crack configuration on the effect of crack closure and propagation rate is examined. Elasto-plastic finite element analysis of the steel sharp notched specimens with a single crack under plane cyclic bending is performed for the different cases of loading. Comparison of numerical results and experimental data has been presented and discussed.
