“…ABAQUS/Explicit software was also used to simulate the deformation for the V-bending process. The parameters of material models are needed to be declared as simulation inputs according to Voce's model equation (1) and corresponding isotropic or kinematic hardening laws similar to above Uni-axial tension/ compression simulation. However, to predict the spring-back phenomenon of V-bending process, the deformed results from Abaqus/Explicit must be used to import into Abaqus/Standard module, 3D Experience ® 2016 HF2 (2016 HF2, Dassault Systèmes Simulia Corp., Providence, RI, USA, 2016) [8].…”

“…In fact, one of the most common processes for sheet metal forming is bending, which is used not only to form pieces such as L, U or V-profiles. Bending process is widely applied in the automotive, shipbuilding, aircraft and defense industries to manufacture any kinds of sheet metal products [1]. In recent years, the high accuracy productions according to the design are a main goal of the sheet metal industry in order to decrease the post-forming processes resulting in cost and time reduction.…”

The spring-back phenomenon is one of the key problems in sheet metal forming process, especially with a complex shape. In this paper, the experiments of spring back have been first carried out to study the effect of punch strokes (different bending angles) on the spring-back angle for 6 (mm) thickness of SS400 sheet steel by V-bending process. The experimental results are then validated by finite element analysis (FEA) of ABAQUS software. To simulate spring-back of V-bending, deformed results of V-shape from a dynamic forming simulation in Abaqus/Explicit would be imported into Abaqus/ Standard, and then a static analysis will calculate the spring-back of V-bending. Simulation studies have shown that there are different variations in the initial bending angle and the spring-back angle after the removal of the bending force based on isotropic and kinematic hardening models. Therefore, the combined hardening model has been proposed to overcome the mismatch between prediction results and the corresponding experiments. Based on the accuracy of FEM simulation, this study also verifies the effect of parameters such as a thickness of the sheet, punch radius and punch stroke on the spring-back angle in order to select the optimum input parameters by using Taguchi method.

This study discusses the phenomenon of spring-back and spring-go in the bending kinematic shaping process using V-bending dies and SGCC galvanized steel sheet (JIS G 3302) material. During the bending process, the zinc layer on the surface of the galvanized steel must not be damaged. The zinc coating on galvanized sheet steel will affect the material forming process (metal forming process). This study employed an experimental design with four input variables: die opening L (mm), punch angle (punch engel), punch speed (punch speed), and bending force (force bending). The input factors for the experiment are 35 mm opening, 40o punch angle, 30 mm/minute punch speed, and 7500 N bending force. In the die opening setting conditions, the maximum spring-back angle is 35 mm, the punch angle is 40 °, the punch speed is 30 mm/minute, and the bending force is 6500 N. The average minimum and maximum spring-back angles in this condition are 0.71o and 4.08o, respectively. The bending force is 7000 N, the punch angle is 50 °, the punch speed is 40 mm/minute, and the minimum spring-go angle is 30o. In die opening parameters, the maximum spring-go angle achieved is 35o, the punch angle is 60o, the punch speed is 50 mm/minute, and the bending force is 700 N. The average minimum and maximum spring-go angles are 1.90o and 6.23o, respectively.
