Comparative analysis of numerical simulation results for the bulk forming of an axisymmetric part using different setups in the LS-DYNA software package

This paper presents the results of finite element modeling of the volumetric stamping process of a glass-type part using solid-state and shell calculation models. The analysis of the stress-deformable state of the 11YUA steel billet during the deep drawing operation is performed. The results obtained by modeling the technological process are presented in diagrams of normal and tangential stresses in the Cartesian coordinate system. The simulation of the deep drawing process was carried out to evaluate the stresses that occur in the workpiece at the time of drawing with initial and boundary conditions that coincide with the real ones. The simulation was carried out in the LS-DYNA numerical simulation package.
