... is extruded first, and the peripheral part of the billet flows later, causing more severe shear deformation. As soon as the force required to push the billet into the container surface exceeds that of the shear strength of the billet material, sticking friction predominates, and deformation proceeds by shear...

... treatments and then pulled to fracture in a tensile test. The bolt at the left was annealed; when pulled, it had much deformation, as evidenced by the necking and thread separation. Fracture was of the cup-and-cone type with a large shear lip, similar to that in Fig. 2 . The bolt at the right...

The rigid body translations and rotations change the orientation of the infinitesimal element but do not contribute to the change of the shape of that element and are therefore not considered in the analysis of true deformation requiring mechanical energy.
