Özet

Subject of this paper is the quasi-analytical treatment of the elastic-plastic spherical shell whose inner surface is heated slowly. The hardening behavior of the material is presumed isotropic, but it need not be specified beyond that. A first plastic region forms at the inner surface, and, for not too thick-walled shells, a second plastic region appears at the outer surface. The general results are specialized to linear hardening and thereafter to Swift's hardening law with the power one half. Numerical results are represented graphically.
