Postbuckling behaviour of rectangular plates under combined loading
AbstractPostbuckling behaviour of perfect and imperfect rectangular plates under biaxial compression combined with lateral pressure is considered.Based on the nonlinear large deflection equations of von Karman plates, the lateral pressure is first converted into an initial deflection by the Galerkin method. The postbuckling behaviour of simply-supported rectangular plates under biaxial compression combined with lateral pressure is then studied using a perturbation technique, taking deflection as its perturbation parameter. Through comparison, it is found that a discrepancy exists between the two cases; with and without lateral pressure. In the case of rectangular plates under uniaxial compression combined with lateral pressure, it is seen that the results obtained from the present paper are quite in accord with other experiments.
