In the sheet metal forming processes, the transformed induced plasticity (TRIP) steel of RAK 40/70 grade exhibits a so-called springback effect, which is governed by strain recovery of material after the load removal. In this study, the numerical simulation of the bending process was performed and compared with experimental data. Springback can be related to many parameters, including forming conditions, tool geometry, sheet thickness, yield stress, work hardening, strain rate sensitivity, and elastic modulus. The effects of the above parameters on the springback effect were evaluated for the V-shaped sheet metal part made of TRIP steel with a thickness of 0.75 mm and a bending angle of 90°. In the numerical simulation, Hill's and Barlat’s yield criterions were used in combination with Ludwik’s and Swift’s hardening models. The numerical simulation data were compared with the experimental results, showing their close correlation.
