摘要

Industry uses the finite element method (FEM) widely for process design to predict metal flow and defects. The accuracy of the input data affects the accuracy of the results from FEM. The true stress-strain curve, also known as the flow stress curve, is one of the critical input variables for process simulation. Valid for small strains, the flow stress curve often is obtained by a tensile test, which was explained in detail in the May/June and July/August issues of STAMPING Journal.
