TriboForm® software evaluation for ArcelorMittal Steel Products

Abstract

In numerical simulations, input data should be correctly defined to enable reliable numerical predictions, close to experimental observations. The purpose of this study is to better take into account the tribological behaviour of ArcelorMittal steel products during the stamping process. TriboForm® is an important additional software solution for the simulation of tribology, friction, and lubrication in sheet metal forming process and enables the generation of multiple friction models. A comparison between experimental observations and numerical predictions was investigated for three ArcelorMittal steel grades (CR4-GI, CR180BH-GI+NIT and CR440Y780T-DH-GI) on several stamping parts. This study illustrates the interest of TriboForm® friction law compared to a standard and constant predefined friction coefficient.
