contact mechanics; friction; abaqus; subroutine; hysteresis; slip reversal

Hello everyone,

I have to use an hysteretic friction model. I am trying to code this in Abaqus by using the FRIC subroutine. The language is Fortran 77.

I am testing my code on a very simple model : two plates sliding on eachother. I apply a 1 cycle sinus displacement at the end of one plate and a apply some boundaries at the other side.
