In this paper we discuss the use of the p-version of the finite 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 finite 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 fields. Presented examples demonstrate that the method can be used reliably with a proper finite element mesh design. Possible extensions of the work are also discussed.
