Determination of stress-intensity factors of fillet-welded T-joints by computer-assisted photoelasticity

  • C. L. Tsai

Fillet-welded T-joints with crack-like discontinuities are analyzed using the photoelasticity method. Stress-intensity factors of opening modes are determined for undercut, overlap and center-line crack of fillet joints with respect to the various loading conditions and the weld dimensions. The photoelastic analysis uses a 20-point overdeterministic approach. The accuracy of fringe measurement is obtained by iteration of the measured results on a pattern-recognition software.
