The output file does note that stress stiffening is on. My displacement vs reaction force graph is very linear all the way through the simulation. (Reaction force is in negative x-direction.)
In the physical specimens, layers did begin to fail right around the 3 mm of displacement. Most had fairly linear force-displacement curves until 3.5 mm or so, and then pretty rapid failure from there. I'm not sure how to change the element type. I am using ACP to model the composite, and ACP only allows the use of surface input geometry. I am then using shell element data in the analysis. I don't know how to use SOLSH190 elements or if it is even possible.
