Analysis by simulation of the stress distribution in different stages of the drawing process of conical parts made from metal sheets
Gheorghe BRABIE, Neculai NANU
Abstract: The stresses generated in the stamped parts before and after the removing of the tools are the main cause that determines the springback of the draw parts made from metal sheets. Hence, to investigate the springback phenomenon it must be known the state of stresses developed in the drawn part by the cold plastic forming. The experimental investigation of the stresses distribution in the case of drawn parts is a difficult problem because of the forming operations and parts geometry complexity. An optimum solution to solve the problem can be the simulation of the forming process and stress distribution. The present paper investigates the distribution of the stresses by simulating the drawing process using ABAQUS software in the case of conical parts made from steel sheets.
Key words: loading stresses, residual stresses, deep drawing.
