DISTRIBUTION OF RESIDUAL STRESSES IN A LAYER CONTAINING A WELDED CYLINDRICAL DISK

摘要

By the method of conventional plastic strains, we study the distribution of residual stresses in a plane layer containing a welded cylindrical disk. For plastic strains symmetric about the median surface of the layer, we perform the numerical analysis of the distribution of residual stresses. It is shown that the radial stresses on the surfaces of the welded joint decrease and the hoop stresses increase as the radius of the disk increases.
