How to achieve creep crack growth in the ABAQUS
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. As the number of damaged elements increases, the damaged eelments distorted too large,as shown in attachment. Therefore, the calculation is stoped.
Does anyone know how to resolove this problem.
