Abstract : The field equation for meridionally inextensional axisymmetric deformations of shells of revolution is developed and applied to the postbuckling analysis of simply-supported imperfect annular plates subjected to compressive edge loads. The semi-inextensional model is then compared with the usual extensional model by using an energy approach with two and three deformation parameters. The method is used to analyse the postbuckling behavior of an imperfect annular plate with an eccentric interior edge stiffener. The results show that although either imperfection or eccentricity lead to stable behavior, their combination may introduce unstable imperfection-sensitive behavior in some cases. (Author)
