The EFB Prize goes to Isabella Pätzold from utg

This year, the EFB Project Award for outstanding scientific and technical research projects went to the Chair of Metal Forming and Casting. Dipl.-Ing. Isabella Pätzold was honored for her research on "Reduction of edge crack sensitivity by two-stage shear cutting".

Within the scope of the project, practice-oriented regression models were developed for dual-phase steel DP800 as well as stainless steel 1.4301 on the basis of experimental data. These enable the selection of a process window, which allows components to be manufactured reliably, even when taking wear into account. Furthermore, they offer the possibility of estimating the residual forming capacity already in the simulative design process and of defining adapted two-stage shear cutting parameters for critical areas in order to safeguard components at an early stage with regard to the formation of edge cracks.

In the project, a simulation model was also set up which enables precise reproduction of the two-stage shear cutting process. Based on a comparison of the experimentally and simulatively obtained results, correlations could be formed, which make it possible to determine adapted two-stage shear cutting parameters with the help of finite element simulation without a high experimental test effort.

The prize will be announced on March 29, 2022, during the colloquium of the European Research Society for Sheet Metal Processing. More information can be found at the following link: (german language)
