Friction is not Constant

Did you know that higher plastic strain actually reduces friction through surface flattening? Understanding these hidden dynamics is why high-fidelity models like TriboForm are becoming essential for modern sheet metal engineering. Relying on a constant Coulomb friction coefficient is no longer enough for the demands of Industry 4.0 and zero-defect production. In sheet metal stamping, friction is a dynamic phenomenon: a complex function of multiple variables! Key Takeaways: • Dynamic variables: Friction changes based on pressure, speed, and heat. • The risk of static models: Constant values often miss critical failure modes in the binder and draw bead regions. • The tribology advantage: Early engineering focus on tribology reduces time-to-market and minimizes physical trial-and-error.
