Does anyone have experience with crack closure modeling? And by the way, Does anyone know whether it is theoretically consistent to model crack closure in the small stran range simply with contact elements?
Dear Enrique García Macias,
See check with my attached paper to see whether it can help your research work. Let me know if you need the Abaqus model associated with this paper.

Dear Xiangxiong Kong
I really appreciate your kind response. I went through that paper and it is truly amazing. Unfortunately, I am not sure it such approach is suitable for my purpose. I am solving an electromechanical problem and I am not so interested in the crack growth as I remain in the very small range. As far as I know, element elimination procedures is somehow similar to continuous damage modeling (like concrete damaged plasticity). However, I think I need to simulate the activation of current flows when the cracks close under compression. In any case, I will investigate a bit in the line of the reference you suggested me. Thanks a lot!

Thanks for explaining, Enrique! I don't have lots of experience in terms of crack closure simulating. It sounds like defining a contact behavior in the model could be feasible, which allowing two sides of the crack can meet and contact each other. I guess you would also like to know how the current flow behave under crack closure, but this is beyond the scope of my knowledge. Good luck!
