Abstract：

Basic material properties of original and annealed 6061 aluminum alloy plates were obtained using uniaxial tensile test. Then the true stress and strain curve of 6061 aluminum alloy was got. The experimental data were fitted with different constitutive equations on this basis, then the results were compared with strain hardening curves of materials. The results show that power function is accurate for the two states of the sheet. Plastic strain ratios for the above plates are 0.996 and 0.712 based on the results from uniaxial tensile test when the true strain is 8%. Besides, a rotary draw bending simulation of 6061 aluminum alloy tube by means of finite element simulation software Dynaform was conducted and the simulation result was analyzed to verify the forming parameters.
