Abstract

In this paper, three dimensional residual stresses due to single pass and multipass fillet welding are analysed by thermal elastic-plastic Finite Element Method. Then, inherent strain distributions produced in fillet welds are expressed by series function with good accuracy. Based on the results of series function, a very simple distribution pattern of inherent strains is proposed and described as functions which only has a few unknown parameters. To determine these parameters by experiments, required measurements will be greatly reduced.
