Two previously undeformed specimens of the same metal are to be plastically deformed by reducing their cross-sectional areas. One has a circular cross section, and the other is rectangular; during deformation, the circular cross section is to remain circular, and the rectangular is to remain rectangular. Their original and deformed dimensions are as follows: Original
dimension
Deformed
dimension
Circular
(diameter, mm)
18.0
15.9
Rectangular
(mm)
20×50
13.7×55.1
Which of these specimens will be the hardest after plastic deformation, and why?
