Thin Spherical Elastic-Plastic Shells under the Action of Concentrated Loads

Abstract

Thin isotropic rotation shells of constant thickness taking into account the appearance of plastic deformations under the local loads are considered. The method of running with discrete orthogonalization is used for the numerical realisation of the present problem. Thin spherical shells with the angle 90 degrees and the relation of the radius to the thickness 100 under local load are considered.
