Finite Element Analysis of Wrinkling and Shearing of Sheet Metal Forming

Objectives: The objective of this work is to perform the sheet metal forming punch and die clearance for the forming of automatic ticket vending machine kiosk. Methods/Analysis: Modeling of sheet metal, punch and die is done. Sheet metal forming simulation is performed using ANSYS LS-DYNA and energy graph were obtained to validate the theoretically obtained clearance values. Findings: Different punch and die clearance values are simulated to show the wrinkling and shearing of sheet metal during the forming process. The theoretically obtained clearance value is verified with Finite Element Analysis (FEA) simulation. Applications/Improvements: This work shows the sheet metal forming and the effect of various punch and die clearance values at the time of forming operation.
