Abstract

The differences of formability with maximum cup depth of drawn product and thickness strain distribution are compared for two kinds of blank shapes which are suggested optimum shape and conventional square shape. The suggested blank is determined by backward tracing technique of rigid-plastic FEM. The deeper cup without wrinkle and flange part could be obtained from the suggested blank shape however the cross sevtion sup from the square blank could not be kept smooth thickness strain distribution and defended those phenomena..
