The kinematic hardening model proposed by Yoshida et.al was applied to the prediction of springback of stainless steel sheet part. From the experiments for the determination of material constant, the anisotropy of plastic-strain-dependent Young's modulus was observed. The prediction accuracy of springback was examined by comparing the calculated results with the experimental results. To take the anisotropy of the plastic-strain-dependent Young's modulus into account, calculations using different material constants at angles of 0°, 45° and 90° from the rolling direction were performed. It was found that the most accurate prediction can be obtained when using the material constant at an angle of 90°, along which the springback occurs. Therefore, the consideration of the anisotropic property of the plastic-strain-dependent Young's modulus was found to be effective for the improvement of prediction accuracy of the springback for stainless steel sheet.
