Some problems of incompressible materials plastic flow simulation

Some problems connected with numerical simulation of incompressible material forming are discussed. It is shown that step-by-step procedure use for solution of non-steady-state metal flow problems led to a greater volume change than the approximately estimated one under incompessibility condition.
