A group-theoretic formulation for symmetric finite elements

After a brief review of the literature on applications of group theory to problems exhibiting symmetry in structural mechanics, an efficient formulation is presented for the computation of matrices for symmetric finite elements. The theory of symmetry groups and their representation allows the vecto...
