Crack growth in abaqus
I'm currently doing analysis of interlaminar crack growth in fibre-reinforced composite by Extended Finite Element Method (XFEM) using Abaqus. I'm a new Abaqus user and therefore I have to familiarise myself by constructing random 2D and 3D models with isotropic materials before jumping onto . Recently, I have worked on the creep crack growth coupled with CDM. In the references, it says that when the element reached to the critical damage, the E of the element was reduced to 0. However, when I used this method in my UMAT, it can achieved creep crack growth in some elements. the mesh. The commercial nite element code, Abaqus, employs XFEM-PN for automated crack growth in a low-cycle fatigue analysis . A fundamental aspect of this thesis is to take a critical look at the code's ability to estimate fatigue fracture life.
