摘要
Abstract
In this paper the flow stress model of ANSI-1043 at room temperature has been got by an experimental method and an interpolation method respectively, then the two models have been used in the research of upsetting process. The research result shows that a precise flow stress model is the preconditions of improving FEM simulation precision. The method of interpolation used in FEM simulation to calculate material flow stress model at different temperature ranges is not scientific, and this will cause great influence of FEM simulation precision.关键词
