Abstract

In this paper, the deformations of a spherical shell caused by the welding of a penetrator or partial sphere are investigated. Experiments were carried out in order to clarity the characteristics of welding deformations and the effects of dimensions of shell and penetrator and welding procedures on the deformation. One dimensional thermal elasto-plastic anaylysis using Rayleigh-Ritz method is applied to the axi-symmetric thermal stres problems of this spherical shell.
