Nonlinear finite element analysis of tubular joints

In this study, important aspects of nonlinear behavior of tubular joints are numerically investigated with a finite element procedure including geometric and material nonlinearities. The numerical results give a clear and convincing physical interpretation of the effects of external loads on the ultimate static strength of tubular joints. The results include the stress redistribution within the joint at the ultimate state, the stiffness of the T-type joints at different load levels, the real failure modes of tubular joints under external loads and the assessment of the safety margins in the design process.
