POSTBUCKLING ANALYSIS OF CIRCULAR PLATES WITH AXISYMMETRIC DELAMINATION AND TRANSVERSE SHEAR DEFORMABILITY

Based on the Von Karman plate theory,the postbuckling governing equations for the axisymmetric laminated cicular plates with delamination are derived.The effect of transverse shear deformation is considered.By using the orthogonal collocation method,the governing equations,boundary conditions and continuity conditions are transformed into a set of nonlinear equations,and the equations are solved with an iterative method.The effects of delamination depth and radius on buckling and post-buckling of the laminated circular plates are discussed.Numerical results are compared with available data.
