This study proposes a simple but effective finite element method to simulate complex 3D crack propagation in quasi-brittle materials such as concrete. Cohesive interface elements, characterized by softening traction-separation constitutive laws, are embedded into initial meshes to model potential cracks. The method is implemented in connection with Abaqus. Various concrete structures under static and dynamic loadings were modeled with excellent results compared with experiments.
