摘要：
The proposed model predicts the damage progress to fatigue failure in cyclic loaded woven composite materials. The relative stiffness is changing per cyclic loading at given stress or strain levels. The correlation between the stiffness degradation rate and the loading parameter is described by a power dependence. The model is validated by experiments performed on ARALDIT/glass tissue and POLIKON/flax tissue composites in fatigue tests; the fatigue damage is recorded by measuring the stiffness changes in the material under this cyclic loading.
