Abstract
A detailed finite element analysis of the hot plane strain compression test has been carried out to investigate the effect of various test parameters on the measured response and deformation. This paper (Part 2) reports the results of three-dimensional finite element simulations of the test, to study the influence on spread of specimen geometry and friction effects. It is found that the spread is more sensitive to specimen breadth than it is to the friction coefficient and initial specimen thickness. Spread is independent of the strain rate of deformation and of the material. It is shown that the empirical relationships used for correcting experimental data for spread during a test are in close agreement with the simulation results.
