Studies on Influence of Cracks on the Dynamic Response of Tubular T-joints for Nondestructive Evaluation

This paper presents an analytical study on the vibration response of tubular T-joints for detecting and sizing of cracks along their intersections. The ABAQUS finite element program was utilized for performing the analysis. Frequency response functions were obtained for joint with and without cracks. The joint was modelled with g-node degenerate shell elements having five degrees of freedom per node. Line spring elements were used to model the crack. The frequency and amplitude changes, as a function of the crack depth and loading frequency for mornent, were investigated in detail.
