摘要：

A simple extension of the thermodynamic dislocation theory is proposed for an analysis of bars subjected to torsion. Employing a small set of physics-based parameters, which we expect to be approximately independent of strain rate and temperature, we are able to simulate the torque-twist curves for bars made of single crystal copper that agree with the experimental ones.
