Abstract
The deformation of aluminum at strain rates from 10−3 sec−1 to 103 sec−1 and temperatures from 300° K to 700° K is studied experimentally under a range of stress states including tension, compression, torsion, and combined tension and torsion. The results from these tests are compared with a generalized constitutive equation developed from the thermally-activated dislocation model of deformation. Predicted functional relationships between the stress, strain and strain-rate invariants and temperature are supported by the experimental data.
