Question:

A steel plate has the dimensions 100 mm × 100 mm × 5 mm thick. It is subjected to biaxial tension of σ1 = σ2 with the stress in the thickness direction of σ3 = 0. What is the largest possible change in volume at yielding, using the von Mises criterion? What would this change in volume be if the plate were made of copper?
