I use the FRIC subroutine to model the pipe-soil interaction and i want to do this with a complex friction curves with peak and slope.
So when i load my curves every step i found a discontinuity in my curve's results in abaqus (Shear stress in function of slip). "Figure in attachment"
I would like to know how can i load my curves in every increment during the STEP in the subroutine to eliminate the discontinuity. "Figure in attachment"

I suggest you to divide your curve according to the lateral displacement. It means that you can define a function for each part and you can implement it in your subroutine code using "IF" command.
Hello
another solution for your case is that you can write directly the load function in your subroutine by means of DISP. Then, this discontinuity will be eliminated.
