A regularized direct symmetric Galerkin BIE formulation for three-dimensional elastoplasticity

Résumé

This paper deals with a symmetric regularized variational boundary/domain formulation for quasi-static 3D elastoplasticity, which is shown to express the stationarity of a certain energy functional. An implicit constitutive integration scheme is implemented. The global consistent tangent operator associated with the non-linear algebraic system of equations is shown to be symmetric.
