Hello, 

Which strain is being plotted? 

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: 

 

Please check exactly which strain is being plotted. 

 

Thank you,

AlexÂ
