Abstract

In this research, the springback phenomenon in the spacer part during the production process and after releasing the part from the forming force was simulated with the help of LS-Dyna software and the finite element method, and the results were verified by experimental testing. In this simulation, the software's Implicit solver was used to simulate the main part of the forming process and to simulate springback. In the definition of the material model for simulation, its anisotropic behavior is ignored and the behavior of the material in the plastic region is described by Holman's power relation. In order to have more parameters for validating the simulation results, four different sheet forming modes were investigated in the experimental test and simulation, and in each of these modes, the speed parameter of the punch, the amount of friction between the tool and the sheet, and the thickness of the used sheet are different. By comparing the results of experimental testing and simulation, an error value of less than 10% has been observed in the calculation of the standard angle for springback
