Abstract

A computer model of deforming a thin axisymmetric shell in Lagrangian-Euler coordinates under consecutive static and pulse loading was created. Consecutive loading reduces the wedging-out of a formed article and increase the stretching degree at the expense of magnification of deforming a flange folding in drawing. Deformation hardening of a material, elastic unloading, interaction of a shell with a dia, wave character of high-speed deforming and other factors are taken into account. An implicit finite-difference algorithm of a numerical solution, taking into account uniformity both features of statement and solution of two problems, was designed and a program was implemented. Calculations and experiments have shown a possibility of application of the computer model in practice of designing combined drawing.
