    A phase field model for ductile fracture considering the strain rate, stress triaxiality and Lode angle parameter

    Ductile materials exhibit rate-dependent behaviors when subjected to different loading rates, particularly during impact and explosion events. In order to investigate the high strain rate behaviors of metal ma...

    A shear-modified cohesive-GTN model for shear failure at high strain rates

    Cohesive zone model is an effective tool for predicting the interface behaviors in materials. However, it is usually defined by the separation without considering the micro-voids nucleation, growth and coalesc...

    Investigation of the Shear Fracture Behaviors of U71Mn at High Strain Rates Using a Shear-Modified Gurson–Tvergaard–Needleman Model

    This paper focuses on the shear fracture behaviors of U71Mn rail steel at high strain rates using a shear-modified Gurson–Tvergaard–Needleman model. Two hat-shaped specimens with different shapes (shape I, sha...
