drawing of cu-al sheet with hardening property

the tensile process is one of the metal forming processes. in this process, the rod or sheet is drawn by applying tensile force and decreases in diameter or thickness after passing through the mold space. the purpose of this study was to investigate the factors affecting the tensile force, double rod with aluminum core and copper shell. the finite element-based diaphragm software was used. the obtained results were compared with experimental values, and the accuracy of the acceptable results was evaluated. increasing the hard work factor means that the metal is softer and requires less tensile strength. the percentage of deformation is directly proportional to the optimum angle of the stretching mold. because the theory calculations are based on the optimal angle of the mold. in the above deformations, the optimum angle value is increased and vice versa. the shell thickness and core diameter also have a direct effect on the amount of tensile force. as the percentage of deformation in the tensile process increases, the frictional power share increases and this increase is lower than the internal force. at the same time, the share of internal power is higher than the rest of us.
