| Abstract Scope |
This study is focused on punch shape design in tube hydro-piercing processes of aluminum alloy A6005 tubes. The flow stresses of the aluminum alloy tubes obtained by tensile tests are used in the finite element simulations of tube hydro-piercing process with software “DEFORM 3D”. The ductile fracture criterion of normalized Cockcroft and Latham is used during the FE simulations. The critical damage values for the criterion are obtained by comparing simulation results and tensile test data. The effects of various parameters such as the stroke, internal pressure, etc. on hydro-piercing processes and deformation mechanism are discussed. Experiments are conducted and the experimental shearing surface heights are compared with the simulation results to verify the validity of the analytical models. The effects of various parameters on shearing surface heights are also discussed by hydro-piercing experiments. |
