FEA of Sheet Metal Forming

Stamping of sheet metal is a highly nonlinear and intricate process involving large deformations, contact interactions, and potential material failure. Ensuring proper die design and forming parameters is critical for optimal results.

In this case study, Tridiagonal’s Finite Element Analysis (FEA) experts leveraged ANSYS LS-DYNA to simulate the real-world forming operation with precision. The team modeled the complete system, including:

• Blank holder force application through simulation

• Accurate friction behavior between blank, die, punch, and holder

• Realistic representation of material flow and deformation

This analysis allowed for early detection of defects like wrinkling and tearing, improving die design and reducing trial-and-error on the shop floor.
