CONTACT BEHAVIOR BETWEEN VESSEL SHELL AND REINFORCEMENT PAD

摘要：

In the analysis of the cylindrical pressure vessels with reinforced pad using thin shell theory, no contact between the pad and vessel is often assumed. It has no enough evidences to verify this hypothesis. Contact behavior between the reinforcement pad and shell under internal pressure, transverse, longitudinal moment separately was simulated by nonlinear finite element technology provided by the software of ANSYS. A comparison of the finite element results with those from experiments shows that the finite element method with contact assumption can predict the stress distribution well. The effect of the gap between the pad and vessel, as well as the effect of the variety of d/D to the contact were also investigated.
