Abstract

An assumed stress 8-node hybrid finite element is presented for buckling analysis. The formulation is based on Hellinger-Reissner variational principle. The element has 24 membrane degrees of freedom and 24 bending degrees of freedom. The stress stiffness matrix is derived by using the Green-Lagrange strains. The element performance is assessed by comparison with numerical examples.
