Elastic Recovery After Plastic Deformation
A cylindrical specimen of a brass alloy 6.8 mm (0.27 in.) in diameter and 80.1 mm (3.16 in.) long is pulled in tension with a force of
4760 N (1070 Ibf); the force is subsequently released.
Compute the final length of the specimen at this time. The tensile stress-strain behavior for this alloy is shown in Animated Figure
7.12.
