Incompressible and nearly-incompressible structures; Anisotropy; Triangular tor element
Abstract :
[en] This paper presents the extension of herrmann's formulation to all cases, isotropic or not, where the local flexibility matrix presents at most one singularity, that is an isotropic pressure. Starting from Reissner's principle, a matrix is introduced, which behaves as the inverse of the flexibility matrix for any deviatoric stress. This matrix may be obtained in a full-automatic scheme. Then, a triangular tor element is developped from this formulation. Finally, tests are presented.
