Influence of material and process parameters on bursting during hydroforming process

Abstract Bursting is predicted using a 3D-necking criterion based on local instability analysis. First, forming limit diagram (FLD) are built to validate the approach and the influence of material parameters is illustrated. Secondly, the criterion is implemented in a finite element code devoted to the simulation of hydroforming processes. Bursting predictions are presented and the influence of process parameters is studied.
