Abstract

This paper analyzes the geometry (crack position, welded joint size and shape, size of specimen) and material heterogeneity effects on the behaviour and integrity assessment of welded plates. The experimental analysis includes plates with small and large surface crack, positioned at different locations in the welded joint. Three-dimensional finite element analyses were applied in solving this problem, and the obtained results were compared with the experiment, thus providing detailed insight in welded plate behaviour and enabling its integrity assessment.

Keywords: welded joint, overmatching, finite element method, weldment, surface crack, structural integrity
