... DEFORMATION If a copper rod is twisted , it will at first behave elastically . But if twisted too much , it deforms permanently . We call this permanent deformation plastic deformation . One can get a shear stress - shear strain curve ...

... deformation then begins if the stress is increased . Such plastic deformation would continue until the rod fractures at point c . The fracture would appear almost the same as if the rod were sawed off perpendicular to the axis . ( The ...
