Abstract
The purpose of this note is to propose an improvement to the widely-us ed Steinberg-Lund model for rate-dependent plasticity. The improved mo del is rate-dependent above, as well as below, the Peierls stress. As a result of this change, one material constant in the Steinberg-Lund m odel acquires a new value, and we thereby obtain a revised estimate fo r the dislocation density in tantalum.
