Crystal plasticity finite element model
WebA crystal plasticity finite element (CPFE) model with Voronoi tessellation was developed to simulate the cyclic plastic deformation considering defect effects. Morrow's model and Smith-Watson-Topper (SWT) model were used to predict the fatigue life and the SWT model was in good agreement with the experimental life between 10 and 10.
