| Abstract: | Based on Reissner-Mindlin plate theory, the buckling and postbuckling analysis of isotropic and orthotropic moderately thick rectangular plates under biaxial compression is presented. The initial geometrical imperfection of plate is taken into account. The analysis uses a perturbatiion technique to determine the interactive buckling loads and postbuckling equilibrium paths. Numerical results are presented that relate to the performance of perfect and imperfect, isotropic and orthotropic moderately thick rectangular plates. |
