Transfer operators for evolving meshes in small strain elasto-placticity Original Research Article

Together with error evaluation and mesh refinement, transfer operators represent the essential component of the adaptive procedure applied to history-dependent materials. Aspects of the transfer operation discussed in this work relate to: equilibrium conditions, consistency with the constitutive equation, geometric issues and diffusion of state variables between successive meshes. In this paper attention is restricted to small strain rate-independent elasto-plasticity. Numerical examples are presented to illustrate some practical features of the computational procedure.
