stress and strain at 0k

Hi

I have equlibrated my ZrH2 at 0k .I would like to calculate stress and strain at this temperature but I am not sure how to do it .I want my structure to deform in one direction and shrink in the remaining so that i can see the necking and cracking

Stress is the pressure, which you can print out with thermodynamic
info. Strain is the box shape/size, which you can also print out.
