Mixed finite element procedures with triangular and quadrilateral elements are evaluated and applied for nonlinear elastic and elastic-plastic analysis of some engineering problems. The elasticplastic analysis involves implementation of von Mises, Drucker---Prager and Cap models. A number of special

Field time integrators with second-order-accurate numerical schemes for both the ยฏuid and the structure are considered for unsteady Euler aeroelastic computations. We show that if these schemes are simply coupled and used straightforwardly with subcycling, then accuracy and stability properties may
