Abstract	Fracture mechanics is the field of mechanics concerned with the study of the formation of cracks in materials. The determination of stress intensity factor (SIF) plays an important role in fracture analysis. This stress intensity factor (SIF) can be determined by experimental, numerical or analytical methods. However, with complicated component and crack geometry or under complex loading only numerical procedures are applicable. In this study, SIF of load-carrying cruciform welded joints has been evaluated using finite element method (FEM). Load-carrying cruciform welded joints with isosceles triangles and non-isosceles triangle fillet weld shapes were considered and have been analyzed by the (FEM) based simulator FRANC2D/L [1] program. Moreover, the effects of the crack position (toe, root or cold lab crack) have been considered. The objective of this paper is to study analytically the effects of variation of crack position as well as the effect of mesh fineness and crack increment on the stress intensity factor (KI) under a constant load for load-carrying cruciform fillet welded joints.
