In this article, the axisymmetric stability of an elastic annular plate with distributed internal heat source under uniform constant compressive radial loading at outer edge is investigated. The governing and compatibility equations are taken from modified Karman’s equations, which solved by shooting method. effect density on critical load investigated discussed in detail. Numerical results wit...

Cylindrical shells under uniaxial compression and spherical shells under equi-biaxial compression display the most extreme buckling sensitivity to imperfections. In engineering practice, the reduction of load carrying capacity due to imperfections is usually addressed by use of a knockdown factor to lower the critical buckling stress estimated or computed without accounting for imperfections. F...

A dynamic statement and a method for numerically solving the buckling problems of elastoplastic shells revolution with filler in axisymmetric non-axisymmetric shapes under quasi-static loading are presented within framework two approaches. In first approach, problem elastic-plastic deformation an elastic combined torsion is formulated two-dimensional (generalized axisymmetric) formulation based...

Abstract Shells of revolution under axisymmetric conditions exhibit a circumferentially uniform pre‐buckling stress state and are important fundamental systems which often serve as reference for those more complex conditions. Given this status, work is continuing on careful complete characterization their buckling response with the aid Reference Resistance Design (RRD) framework ultimate benefi...
