Example: Consider a metal whose strain hardening behavior follows: 25,000 0.25 psi. If an annealed bar of this metal is pulled in a tension test from a starting dia. of 12.7mm to a dia. of 11.5mm (uniform elongation, no friction, no distortion), what is the work per unit volume required? If the bar is reduced by extruding and the deformation efficiency is 70%, what is the extrusion pressure?

Question
Example: Consider a metal whose strain hardening
behavior follows: 25,000 0.25 psi.
If an annealed bar of this metal is pulled in a tension
test from a starting dia. of 12.7mm to a dia. of 11.5mm
(uniform elongation, no friction, no distortion), what is
the work per unit volume required?
If the bar is reduced by extruding and the deformation
efficiency is 70%, what is the extrusion pressure?
