Elastic Recovery after Plastic Deformation 6.49 A cylindrical specimen of a brass alloy 7.8 mm in diameter and 95.0 mm long is pulled in ten- sion with a force of 6000 N; the force is subse- quently released. (a) Compute the final length of the specimen at this time. The tensile stress-strain behavior for this alloy is shown in Figure 6.12. (b) Compute the final specimen length when the load is increased to 16,500 N and then re- leased.
