BUCKLING AND POST BUCKLING ANALYSIS OF THIN PLATES

Abstract

This work presented the effects of buckling and postbuckling behavior of rectangular plate under uniaxial loading. An overview of past research is presented, and several key findings and behavioral characteristics are discussed. These findings include the effects of shape, eccentricity, aspect ratio, loading, and boundary conditions. Some over all important findings of these studies are that plates that loads for corresponding plates with different boundary condition and uniaxial loading in buckling and post buckling load-carrying capability. The critical buckling load is obtained adopting Galerkin’s approximation. The postbuckling equilibrium path is obtained by solving non linear algebraic equation with the help of Newton –Raphson method. The Von Karman theory is used for non linearities and initial geometric imperfections.
