Abstract
Conventional phenomenological models of composite laminates often require a large amount of experimental data due to the dependence on stress level. In this study, a new generalized model capable of predicting the material property degradation at each stress level using a single set of parameters is proposed to dramatically subside the experimental cost. Furthermore, two sets of residual strength data and one set of residual stiffness data are adopted to validate the proposed model. The results show that the new model is capable of predicting both residual strength and stiffness at arbitrary stress levels using single set of model parameters.
