Three-Dimensional Data Transfer Operators in Plasticity Using SPR Technique with C0, C1 and C2 Continuity

Abstract

In this paper, the data transfer operators are developed in three-dimensional elasto-plasticity using the Superconvergent Patch Recovery (SPR) method. The transfer operators are de ned for mapping of the state and internal variables between di erent meshes. The internal variables are transferred from Gauss points of old mesh to the nodal points. The variables are then transferred from the nodal points of old mesh to the nodal points of new mesh. Finally, the values are computed at the Gauss points of new mesh using their values at the nodal points. Aspects of the transfer operators are presented in a three-dimensional superconvergent path recovery technique, based on C0, C1 and C2 continuity. Finally, the e ciency of the computational algorithms is demonstrated using a circular tube subjected to internal pressure.
