— In the present investigation the ultimate capacity of cracked tubular T‐joints, loaded in tension or out‐of‐plane bending, is computed by means of non‐linear finite shell element analyses. The cracks are accounted for using inelastic line springs. The calculated results are compared to corresponding test data and other published case computations. Global load‐displacement behaviour and local behaviour by means of the J integral are utilised for the cracked joints. The analyses demonstrate the feasibility of the FE analyses in assessing the joint capacity, but some deficiencies in the modelling are pointed out.
