a. A specimen of initial length /Q is first plastically extended to I/Q. Then it is further stretched until the final length is 3 /Q . Calculate both the engineering and true strains after each stage of deformation and cumulatively. b. The specimen is compressed from /Q to HQ. Again, compare both strains.
