Abstract

This paper describes the fatigue life computation and comparisons of welded structures made up of high strength steels. Fatigue life of a T-joint two side fillet welded component is computed with four different methods. The methods used for investigation are nominal stress method, effective notch method, structural stress method and simple fracture mechanics method. To investigate the problem using structural stress and effective notch method, a fillet welded plate is modeled in ANSYS software and two-dimensional linear elastic analysis is performed. The fatigue lives obtained with these methods are reported and compared with the results obtained from nominal stress and simple fracture mechanics approach.
