In this study, a strain-rate dependent micromechanical constitutive model has been presented to predict the dynamic behavior of composite laminates. First, strain rate dependent mechanical behavior of neat polymers was characterized by a dynamic constitutive model. By combining this model and the bridging matrix method, a dynamic micromechanical constitutive model for predicting mechanical behavior of unidirectional composites was developed. Then, using a dynamic progressive model for fiberreinforced composites, mechanical properties of composite laminates were predicted at different strain rates. In order to validate the present model, predicted results were compared with available experimental data. It was shown that the present constitutive model was able to predict the dynamic mechanical properties of composite laminates with an acceptable accuracy.
