An algorithm for determining the optimal blank shape for the deep drawing of aluminum cups

In the deep drawing of cups, the earing defect is caused by planar anisotropy in the sheet and friction between the blank and punch/die. In the past, several incomplete research efforts have been directed toward predicting an optimal blank shape that will avoid the formation of ears. In this paper,...
