The common junction of three dissimilar general shells of revolution is angyzed. Asisymmetric loading may be in the form of surface forees, concentrated forces and moments at the junction, and arbitrary thermal gradients. Basic differential equations available for elastic shells are extended for application in the elastic-plastic regime. The von Mises-Hencky yield criterion, deformation theory of plasticity, and successive approximations are used to determine plastic strains. Postyield material
