FOR5134 - Solidification cracks during laser beam welding

The main objective of FOR5134 is to develop a process understanding on the formation of solidification cracks and their correlation to process parameters. For this purpose, the relevant phenomena from macro to meso and down to the micro scale are to be mapped in a quantitative process model. With this model, mechanisms of solidification crack formation should be identified and correlated with process parameters in order to enable a prediction of solidification crack probabilities. The research unit is composed of scientists from various disciplines in the fields of mechanical engineering, production engineering, materials science, mathematics and computer science. Seven research institutions at five German locations are involved in the interdisciplinary collaboration: - Federal Institute for Materials Research and Testing (BAM) - Chair of Photonic Technologies (LPT) at the Friedrich Alexander University of Erlangen - Chair of Computer Science 10 (Systems Simulation) (LSS) at the Friedrich Alexander University of Erlangen-Nuremberg - Institute of Mechanics (IfM) at the University of Duisburg-. Essen - Chair of Numerical Mathematics and Scientific Computing (NuMWiR) at the University of Cologne - Institute for Digital Materials Research (IDM) at the University of Karlsruhe - Chair of Engineering Mechanics (LTM) at the Technical University of Kaiserslautern
