A subsidence of circular cylinders between rigid stamps at creep conditions is studied. There are three different material models. Appearance of barrel shape form is allowed (this decision is realized on the basis of package LS-DYNA). Calculations of all principal parameters were carried out at two loading programs: at constant speed of the cylinders' bases coming together and at constant compressing force. Calculations have shown that the energy, spent on subsidence of the cylinder during the first loading variant isless, than in the second variant (this difference in certain processes is equal to 8–10%).
Keywords: circular cylinders, material models, shortening, creep, barrel shape form.
