Use of the method of slip bands for analysis of stress-strain state in the 《active》zone in welding

摘要

The applicability of the theory of slip bands (yield bands) for analysis of the stress-strain state in plastic deformation development during welding, was shown. It was determined, that with the increase of the welding speed with a constant effective heat power the trajectory of radial slip bands is changed, the length of the transverse bands is reduced, and the level of longitudinal stresses increases up to the value of 1.15 of the material yield point.
