Abstract:

This study utilized a computerized universal testing machine to obtain the stress-strain curves and fracture behavior of AZ31 magnesium alloy at various temperatures. Additionally, friction coefficients were determined through friction tests conducted at these different temperatures. Ductile fracture analysis was performed during the graphite-lubricated hemispherical deep drawing process at various elevated temperatures. By employing finite element simulation combined with ductile fracture criteria, we determined the forming load, punch stroke, and fracture location for AZ31 sheet metal forming at different working temperatures. Finally, the predicted values from the simulation were compared with experimental results obtained during the hemispherical deep drawing process. The simulation results showed good agreement with the experimental values for both the punch stroke and the fracture location during the hemispherical deep drawing process. This consistency confirms the feasibility of the method for predicting ductile fracture during deep drawing at various elevated temperatures.
