摘要

Part 2 of this series of papers presents an analytical model for regular planar polygon tube hydroforming (THF) as a special case of the analytical model for symmetric multi-nose tube hydroforming. The governing equations derived for multi-nose THF in Part 1 were evaluated by taking the limit of die geometric variables, resulting in a new set of governing equations for regular polygon THF. The model was validated using finite element analysis and a THF experiment, where good agreement was obtained. The model is able to predict field variables such as stresses and strain distribution, thinning rate distribution, and deformed shape at a particular pressure.
