In this work, we developed the simulation method for ductile materials by using damage model and finite cover method(Finite Cover Method: FCM). Estimating the ductile behavior of materials and structures is basic interest in many fields of engineering. In nowadays, a lot of models to predict the ductile fracture have been developed. The damage model, which based on the continuum damage mechanics assumes the microscopic mechanism of the fracture as the damage evolution. However, the proposed simulations by using the damage model are not good at describing the discontinuous surfaces. Hence, the finite cover method(FCM) is one of the candidate for the implementation to generate the discontinuous surfaces. To simulate the process (e.g., crack generation or propagation of the discontinuous surfaces ) of the ductile fracture, we implement the damage model to our FCM codes.
