In order to incorporate geometric nonlinearity into rigid-plastic continuum elements during a step, we introduce the convected coordinate system. To show the stability of strain distributions under the effect of geometric nonlinearity according to incremental step size, two sheet metal forming processes, stretching and deep drawing process, are analyzed with various step sizes. Then the computed results are compared with those obtained without considering geometric nonlinearity.
