Abstract

Compared to recent advances in the performance of quadrilateral elements, shear deformable triangular elements fall far behind with respect to accuracy and computational efficiency. One aim of the present paper is to investigate why triangular elements are more difficult to improve than quadrilateral elements. An overview of the most important techniques to improve the element performance is given. Recent developments of low order triangular elements for membranes and plate bending are summarized. A new 9-dof membrane element combining Bergan's "Free Formulation" and Simo's EAS-method is proposed. A variety of 3-node triangular plate, membrane and facet shell elements is compared by several numerical examples. The current study is restricted to linear elastic structural response.
