Hello there

I have a problem with three point bending analysis in apdl.
I have a model metal coating with ceramic and this materials bonded with polymer adhesives. Thus, my codes on apdl are;

This is my codes that I wrote. But I do my analysis like as laminated composite and include constant force.How can I make my analysis as nonlinear. Force will change 0 to 40 N. And coated material can analyse like laminated composite analysis method?

From now thanks for your help and interest.
