Study of the distribution of tensions in lap joints welded with lateral beads, employing three dimensional finite elements
This paper investigates the distribution of tensions in lateral beads joining lap welded plates, transmitting forces parallel to the axis of the beads. The research is done along the throat plane of the bead. Finite element technique is employed, doing a three dimensional analysis with volumetric elements, modelling the whole geometry of the joint exactly, i.e., plates and beads. This analysis shows a differential behaviour along the throat plane of the bead, in its length and thickness, noted in the norms, but not considered in structural design.
