Abstract
Plane strain extrusion has been used to generate large tensile strains that would not be possible to achieve in a uniaxial test. The deforma tion has been analysed by assuming that the plastic strain occurs by s liding at a small angle relative to the stress characteristics. Calcul ations to find the amount of permanent dilation are compared with the experimental data. The results of the extrusion are consistent with pr evious tests on uniaxial specimens that were strained at low levels.
