The mechanical properties of composite materials degrade progressively with the increasing of the number of cyclic loadings. Based on the stiffness degradation rule of composites, a phenomenological fatigue damage model is presented in this paper, which contains two material parameters. They are pro
Generic microstructures are represented via a two-dimensional discrete lattice of linear-elastic springs with a Normal distribution of static strengths. These springs represent grain boundaries and damage is constrained to intergranular cracking. The fatigue behavior is described with a Basquin law
According to the law of thermodynamics, a new damage evolution equation is advanced in the present study to predict the fatigue life of the Pitch-Change-Link component. As its premise, the fatigue life prediction method for smooth specimens under the repeated loading with constant strain amplitude i
