This article describes a recently started research project about the rolling of small and very thin strip, or in other words the production of micro strip using flat rolling processes. Main subject of the article is the finite element simulation of the production process and its validation. First the practical relevance of micro strip and its production process are presented. Furthermore the scaling effects which miniaturisation brings with it are introduced. Determination and consideration of the size effects are essentials in order to make optimisation possible. It is proposed to determine the size effects in the flow curve with a miniaturised multi‐layer plane strain compression test. The simulation will be done on a continuum base which includes the determined size effects out of the multi‐layer plane strain compression test. Finally a comparison of the FEM‐simulation results (rolling force, cross sectional geometry) with real processes validates the modified finite element simulation.
