The strain and strain rate dependence of the yield stress of aluminum

Abstract

The plastic properties of aluminum (99.5 %) are considered. Using the hardening curves (for strain rates of 0.25, 0.4, and 63.0 s −1), analytic dependences of the yield stress of aluminum on strain (in the range between 0.0 and 0.5) and strain rate (in the range between 0.25 and 63.0 s−1) have been found.
