摘要：
A numerical model is presented for analysing cohesive cracks under both quasi-static and dynamic loadings. The displacement discontinuities across the cohesive crack are captured independently of the finite element mesh structure. This overcomes the difficulties associated with using finite elements when simulating propagating cohesive cracks. The model is derived in a consistent manner from the weak equation of motion, with minimal assumptions. The performance of the model is shown through examples under both quasi-static and impact loading.
