Finite element analysis of tubular joints in offshore structures

S O Abuodha, F M Burdekin

Abstract


This research work was involved in the finite element tool to determine the ultimate strength of initially uncorked joints, which fail by development of tearing fracture at the weld toe. The local approach methodology in contrast to classical fracture mechanics was used. Finite element analysis was done of T-joint plate geometries, representing a 2-D model of the joint between the brace and the chord walls. This was subsequently followed but finite element analysis of six tubular joints. A global analysis was initially undertaken, then the submodel analysis carried in the areas of stress concentration.
