A Study for the Fatigue Failure Mode Assessment of Fillet Weldments

Abstract:

In this study, a methodology for the assessment of fatigue failure modes of weldments due to partial penetration weld has been carried out by using structural stress method. Structural stress calculation procedure, using shell element based on equilibrium consideration using nodal forces and moments, is employed. It is important to note that the structural stress calculation procedures for partial penetration welds can be used to determine a minimum weld leg length, beyond which, weld root failure modes can be effectively suppressed. An example study, with respect to a fillet weld leg length design, is compared with a design criterion, and they are found to be in agreement.
