Homework 2.1. Take a cubic piece of metal with a side length lo and deform it plastically to the shape of a rectangular parallelepiped of dimensions l1, l2, and l3. Assuming that the material is rigid and perfectly plastic, show that volume constancy requires that the following expression be satisfied:ε1 + ε2 + ε3 = 0. (2’)2. The following data are taken from a stainless steel tension-test specimen: (4’)Also, Ao = 0.056 in2, Af = 0.016 in2, lo = 2in. Plot the true stress-true strain curve for thematerial.3. What are the properties commonly associated with metallic materials, ceramic materials and plastic materials respectively? (3’)4. You are given the K and n values of two different materials. Is this information sufficient to
