✦ Synopsis

In this paper we discuss the use of the p-version of the ®nite element method applied to elastoplastic problems that exhibit sharp (but continuous) deformation gradients. The deformation theory of deviatoric, linearly hardening elastoplasticity with an iterative, displacement based ®nite element framework is used. The focus of this work is on assessing the applicability of the p-version to the analysis of localized deformation with continuous strain and displacement ®elds. Presented examples demonstrate that the method can be used reliably with a proper ®nite element mesh design. Possible extensions of the work are also discussed.
