Abstract
Recently, high speed tensile test is being recognized as a standard testing method to confirm the strength under dynamic loads for engineering plastics. In our previous study, elastic strain rate concentrations are discussed by FEM. In this study, elastic-plastic FEM analysis is performed to confirm the real strain rate appearing at the notch root. Then, the master curve for the final fracture elongation for polycarbonate is constructed. It is found that the fracture behavior can be predicted for the wide range of impact speed under various temperatures from the master curve based on elastic-plastic analysis.
