Abstract
A mathematical model of the determination of thermal stresses in the case of local thermal loading of two intersecting cylindrical rotational shells with a variable wall thickness is given. The suggested model can be taken as a rough estimate of thermal stresses generated in the welding of discharge components (nozzles, flanges, sleeves, etc.) of high-pressure vessels. Special features of these designs, consisting in their nonuniform thickness and sharp recontouring in the longitudinal section of the load-bearing and diverting elements, conditioned by the technological necessity of the shapes of the structural parts, are taken into account.
