Topic: Single fibre pull out modeling
Hello, I want to make single fibre pull out model.
(single PP fibra is pulling out from 10x10x10cm concrete cube.)
So far I found cohesion parameter with which i get correct max load (comparing with lab results),
but after that my (Y=Load X=Displacement) graph drops (Load force) immediately down . I want to make such model that form from max N it would be slowly fall down to min force. How do i achieve this? Should I modify cohesion softening/hardening in 3D inteface? Or some other way modify bond slip?
