A cumulativedamagemodel is proposed, which can be used to consider the influence of in plane bi-axial stresses and mean stress on the fatigue behavior of unidirectional laminates.
推荐了一种应变损伤累积模型,能够考虑单向板面内多轴应力和平均应力的影响。

Taking into account of the effect of loading history, a new nonlinear cumulativedamagemodel is established and the steps to predict remaining fatigue life with the model is given.
Fatigue reliability interference model is established based on fuzzy cumulativedamage of components, then general formula and simulation methods of fuzzy reliability estimation are derived.
