Textbook Question
Chapter 3, Problem 26QTP
If we assume that all the work done in plastic deformation is converted into heat, the temperature rise in a workpiece is (1) directly proportional to the work done per unit volume and (2) inversely proportional to the product of the specific heat and the density of the workpiece. Using Fig. 2.5, and letting the areas under the curves be the unit work done, calculate the temperature rise for (a) 8650 steel, (b) 304 stainless steel, and (c) 1100-H14 aluminum.

A cylindrical specimen of brass that has a diameter of 20 mm, a tensile modulus of 110 GPa, and a Poisson's ratio of 0.35 is pulled in tension with a force of 40, 000 N. If the deformation is totally elastic and the original length is 120 mm, what is the final length of the specimen in mm?
Do you expect a material's stiffness to increase or decrease if there is more than one deformation mechanism occuring? Why?
A paper clip is made of wire 0.7 mm in diameter. If the original material from which thewire is made is a rod 25 mm in diameter, calculate the longitudinal engineering and truestrains that the wire has undergone during processing.
