I am trying to model the damage evolution in a bolted connection in Abaqus with element deletion option. I have the stress-strain data for the bolt but not sure how to extract the required inputs necessary to model the damage or the fracture in the bolt. Below is a short explination for how I did the modeling:
Material - mechanical - damage for ductile metals - shear damage.
Then, a window opened asking to enter the material parameter (ks), fracture strain, shear stress ratio, and strain rate. (see attached photo).
After that in order to model the damage evolution, I selected sup-option and it asked me for the displacement at failure. (see the attached photo).
I do not know how or from where I can get these values. I tried to read about the damage mechanics but could not get how obtain these values. Are there any resources that can help or any examples or explanations?
