| Abstract Scope |
In this study, multi-stage hot deep drawing of an SS304 sheet of 0.5mm thick at elevated temperatures (500-1000oC) has been investigated numerically and experimentally. Initially, uniaxial tensile properties and the plastic strain ratio of the SS304 sheet was evaluated at different temperatures. These experimental values were then used in a finite element (FE) simulation to simulate the multi-stage hot deep drawing process. The results obtained from the simulation, such as blank holding force, peak deep drawing force, distribution of strain were discussed. A strain non-uniformity index (SNI) was used to predict failure of the deep-drawn cup during deformation at elevated temperatures. In addition, the effect of blank holding force and temperature on wrinkling, earing and thinning of the deep drawn-cup were analyzed. Finally, the required deep drawn cup has been manufactured based on the outcomes of the numerical simulation of deformation of the SS304 sheet. |
