The effects of tensile softening curve parameters on the crack propagation P-CMOD and P-CTOD curves were analyzed using a calculation method which adopted the initial fracture toughness as the crack propagation criterion. The results showed that: the

The paper proposed a method to generate the finite element mesh of concrete at meso level semi-automatically. And an aggregate meshing computer program, AggMesh, was developed by C++ language. Since it avoids the judgment of node coincidence in conta
