Abstract

In this paper, the effect of residual stresses and weld geometry on the fatigue life of butt welded joints was studied by developing an analytical model using Linear Elastic Fracture Mechanics (LEFM), superposition and finite element approaches. Various configurations of residual stresses and weld geometry in butt welded joints were considered andcorresponding effective stress intensity factors were calculated by using Bueckner's and Kanazawa's weight functions for an edge and a central through-thickness crack in finite plate respectively and Newman-Raju's empirical equation was used for semi-elliptical surface crack. Fatigue life of bun welds subjected to various weld geometries and residual stress configurations in as-welded condition and post-weld treatedcondition were calculated by using Paris' law with the effective range of stress intensity factor for zero-to-tensile loading (R=0) and compared with the available experimental data.
