Abstract

The aim of this research project consists of the application accuracy improvement of the numerical simulation with coexistent increase of the effectivity of the material characterization. With a part‑specific choice of the testing methods, the use of additional information of standardized tests (e.g. continuous progress of the Lankford coefficient) as well as by a material-specific modelling of yield loci and subsequent yield loci (e.g. tailored yield criterion exponent / m-value) results a rise of the prediction quality of numerical sheet metal forming processes and additional a time and cost reduction during the experimental value determination. The obtained findings are directly transferable and provide therefore a straightaway benefit for small and medium-sized businesses.
