There are shown the results of application of an axisymmetric rigid-plastic finite element membrane model to the analysis of a circular steel sheet stretching process under action of a punch with profile, which consists of two circular arcs with small radii. The failure of the deformed shell is computationally revealed in the form of strain localization.
