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

In this paper, the data transfer operators are developed in three-dimensional elasto-plasticityusing the superconvergent patch recovery (spr) method. the transfer operators are definedfor mapping of the state and internal variables between different meshes. the internal variablesare transferred from gauss points of old mesh to the nodal points. the variables are thentransferred from the nodal points of old mesh to the nodal points of new mesh. finally, the valuesare computed at the gauss points of new mesh using their values at the nodal points. aspectsof the transfer operators are presented in a three-dimensional superconvergent path recoverytechnique, based on co, c1 and c2 continuity. finally, the efficiency of the computationalalgorithms is demonstrated using a circular tube subjected to internal pressure
