Summary:

A computation tool for hydroforming prediction using an inverse approach (IA) has been developed. This approach is based on the method proposed by Guo and others [1], however it has been extended to tube hydroforming problems in which the initial shape is not flat but is a round tube subject to internal pressure and axial feeds [2]. Although the inverse method tool is a stand-alone code, it has been linked to the Marc code for meshing purposes and visualization of results. In this paper, a finite element analysis of an extruded AA 6061-T4 tube submitted to free hydroforming conditions is carried out using the IA code. The results are in good agreement with those obtained by an incremental approach. However, the computational time in the inverse procedure is much less than that in the incremental method
