    Abstract

    A method is described for the determination of the distribution of strain within a specimen undergoing large finite, nonuniform deformations under plane strain compression. The method has been applied to the hot deformation of an aluminum alloy. Results show that prior strain history has no effect on the strain distribution and that specimens of a larger tool width to specimen thickness ratio provide more homogeneous strain distributions. It is proposed that variations in stress-strain curves observed for different tool width to specimen thickness ratios arise from the inhomogeneity of deformation and that these variations are greater in work-hardening materials. Implications for metallographic studies are drawn.
