Effects of the transverse stress on biaxial fatigue crack growth predicted by plasticity-corrected stress intensity factor

摘要: Abstract The transverse stress has an important effect on the biaxial fatigue crack behavior. However, experimental evidence provided conflicting indications: it is sometimes considered to increase, decrease or have no effect. These complex phenomena cannot be rationally explained by existing mechanical models. of growth behavior still one most puzzling questions in fatigue. Physically, this a induced plasticity phenomenon. In paper, plasticity-corrected intensity factor (PC-SIF) proposed describe By use new driving force some associated with are predicted. Comparisons results showed that PC-SIF as effective parameter capable predicting effects length, level, cyclic ratio, ratio and phase difference growth. Consequently, alleged been PC-SIF.
