A Fully Regularized Direct Boundary Formulation For Three-dimensional Elastoplastic Problems
Résumé
The present work is devoted to a fully regularized boundary formulation for three-dimensional elastoplastic problems. The proposed algorithm is based on an integral representation of the strain field in which no integrals have to be understood in the principal value sense. Following the current approach used in Finite Element procedures, an initial strain formulation and an implicit integration scheme are considered. The elastoplastic relationships take into account an isotropic and linear kinematic hardening material satisfying the von Mises criterion.
