Implantation et validation de l’élément fini SHB8 dans ABAQUS

Abstract

The "SHB8" continuum shell element is an under integrated element, stabilized then projected by the "Assumed Strain Method ". Its good experience feedback compared to the standard elements of INCA and ASTER led us to implement it in the ABAQUS code using the UEL subroutine. Its performances are again checked on linear static patch tests. Compared to the ABAQUS elements: C3D8I and S4, the "SHB8" presents a fast convergence even for coarse mesh.
