Abstract

A nonlinear finite element analysis is carried out for the whole process of elastoplastic deformation considering both material and geometry nonlinearity, and the limit states of damage and failure mechanism were studied. According to the analysis, the joints studied show great bearing capacity, which can meet the requirements of the target load and there is a certain security reserve. The results show that the load increased with severe stress concentration at certain parts of the joints. The junction between ring stiffeners, gusset plates and tube walls first come into the plastic stage, and with the increase of load the plastic zone spread out across the entire tube wall which leads to the final failure of the joint.
