Hello,Â
Which strain is being plotted?Â
After running a simple shear model and plotting the strains I got the following results. If the Cauchy strain is plotted (computed by LS-DYNA), the graph should look like this:
If the engineering (infinitesimal) strain is plotted (computed by LS-PrePost) it will be of course linear:Â
Â
Please check exactly which strain is being plotted.Â

Thank you,
