Abstract

The results of research mode of the “dangerous” pre-destruction zones at the root of cruciform weld joint are presented. A technique for determining the areas of “dangerous” zones in numerical simulation is proposed. The engineering equation to determine the area of the danger zone as a result of numerical modeling of the elastoplastic problem is received.

Keywords
