A large rotation shell theory with six independent parameters considering arbitrary rotations is implemented for buckling and post-buckling analysis of panels based on first-order shear deformation (FOSD) hypothesis. The results obtained by the proposed large rotation theory are compared with those by moderate rotation theory.
