| Abstract: | An investigation was made to the critical fracture load and limit drawing ratio of the deep-drawing of cylindrical cups with flat-nosed punch. Four different solutions of the critical fracture load were compared. The influence of various parameters on the critical fracture load is given. Two empirical formulas proposed for calculating critical fracture load and limit drawing ratio are simple and applicable. It can be widely used in practical production and in the design of technological process and dies. |
