The effect of temperature and loading history on the compressive stress–strain properties of two plastics is described. Polypropylene and nylon cylindrical specimens were reduced in height by 20%, 40%, 60%, and 80%, at room temperature and 25°F below the melt point and at two different deformation rates. Test specimens were cut from these worked billets along two directions, axially and radially. Subsequent compressive stress–strain tests were run using an Instron tester. Results of these tests are presented and compared with the stress–strain curve of the virgin material.
