【 摘 要 】

A two-parameter damage model based on residual strength, applied stress and cycle ratio is presented in this paper to predict progression of damage at different stress levels. Using the proposed model, damage factor progression was predicted for E-glass/vinyl ester laminate at three different stress levels. It is observed that proposed model predicts the damage progression closely even though it is not reporting the type of damage. Also, the damage is reported even at low cycles of loading because of anisotropic nature and inherent damages present in the composite materials.
