บทคัดย่อ

In sheet metal forming process of Advanced High Strength (AHS) steels, springback effect is one of the most critical problems for manufacturer. The springback of a formed part occurs due to residual stress released after deformation. FE simulations were often used to describe both forming and springback behavior of steel sheets. Recently, the Yoshida-Uemori (Y-U) kinematic hardening model has been successfully applied for the springback simulation. The model is capable of reproducing the transient Bauschinger effect, permanent softening and work hardening stagnation during a large deformation. In this work, method for determining materials parameter of the Y-U model was briefly presented. Initially, cyclic tests were performed under both tension and compression loads for the high strength steel grade JSC780Y and JSC980Y. FE simulations of 1-element model were carried in order to investigate predicted cyclic stress strain curves. Both Y-U model and a mixed isotropic-kinematic Barlat2000 model were used in the simulations. Stamping tests of hat shape sample were carried out for verifying the experimental and numerical results. It was found that the Y-U model provided more accurate springback results than the other model. ฉ 2014 SPIE.
