Project details
Short description
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.
