Two commonly used approaches to model fatigue damage are residual stiffness and the residual strength approach. In this paper, residual stiffness and the residual strength model is simulated. The model approach is in way: the damage growth rate-a measure for stiffness loss- is expressed by two separate terms representing the initiation and propagation phase of damage respectively. The model is capable of simulating the three stages of stiffness degradation: initial decline, gradual reduction, and final failure, as well as the stress redistribution due to the loss of stiffness in the damaged zones. The experiment also was carried out in this study. | Item Type: | Journal |
