Abstract

Strain-localization in welded joints is investigated in low-carbon steel polycrystals under static tensile and cycle fatigue loading. The basic types of mesostructures formed at different stages of continuity disruption are described. The formation of a band of localized plastic deformation has been found to precede that of the main fatigue crack. It is shown that the mechanical state of a loaded welded joint can be diagnosed experimentally and its residual lifetime can be predicted.
