In this paper, an advanced computational framework is presented for integrated simulation of hydroforming effects and welding assembly operations. The finite element procedures take advantages of existing commercial finite element codes such as ABAQUS by employing a series of user-developed interface modules and a unified material constitutive model formulated with internal state variables that are used to track stress/strain histories induced during forming and welding operations. Its applications in design and welding assembly of hydrofomed components are demonstrated with a series of selected case studies. Based on the detailed finite element simulations described in the above, the following important observations can be made:
