• ABSTRACT: In this study hydroforming analysis of low carbon cold formed structural steel sheets (St12, SAE 1006) are studied experimentally and numerically. The effects of hydrostatic pressure, plate thickness, mould curvatures were investigated. The failure zones, stress and deformations were compared with finite element model. It was found that the metal elongation and strength, plate thickness, mould design were effective tools for hydforming performance of sheet metals. The Bilinear isotropic hardening nonlinear material modelling with shell elements are used in Ansys 16.0 Lsdyna explicit module. The effects of element size on stress results and thinning of sheet metals at plastically deformed place are also discussed in model. The results are found in good agreement with the results of experimental works.
