説明

<jats:p>The topography of the sheet metal and tool surface influences the contact behavior between the tool and the sheet metal. With a simulation on the micrometer scale the topographical deformation of the sheet metal is elasto-plastically modeled using an explicit finite element method. The model of the lubricant in between is based on a simplified method calculating the pressure and velocity of the liquid with Darcy’s law. A flat rigid tool is pressed on the sheet metal surface simultaneously with a constant lateral motion. Simulations were performed with real and modeled surfaces. The topographies show different tribological behavior depending on their texture.</jats:p>
