Lay Summary (English)

Lay summary

The aim of the project is to develop an experimentally validated computational method based on the crystal plasticity finite element (CPFE) method to simulate cyclic plastic deformation as occurs during low cycle fatigue in fcc materials. CPFE is an excellent computational tool that is depending on the constitutive input applicable for mechanical engineering issues as well as for the simulation of fundamental plasticity. Fatigue is a phenomenon of broad technological importance and poses a limit to the lifetime of engineering components. A CPFE model of the cyclic plastic deformation occurring during low cycle fatigue is expected to elucidate the relation between the microstructural details (like the crystal orientation distribution) of the material and the process of crack initiation as part of fatigue. The uniqueness of the project is that it aims to develop a CPFE model for fatigue simulations with a constitutive input that is based on in-situ Laue experiments completed with electron back scatter diffraction (EBSD), electron channeling contrast imaging (ECCI) and transmission electron microscopy (TEM) analyses. The project is an international collaboration educating three PhD students, two at the Paul Scherrer Institute in Switzerland and one at the Max-Planck-Institute für Eisenforschung in Germany.

Abstract

The current proposal is a synergetic approach between three research groups:- Dr. K. Janssens (LNM-NES-PSI),- Prof. H. Van Swygenhoven, Dr. S. Van Petegem (MSS-NUM-PSI),- Dr. S. Sandlöbes (MPIE)and requests funding for three PhD students:- PhD student I is to focus on crystal plasticity finite element (CPFE), enrolled at the EPFL with Prof. Helena Van Swygenhoven as thesis director, and co-supervised by Dr. K. Janssens.- PhD student II on the Laue experiments, enrolled at the EPFL with Prof. Helena Van Swygenhoven as thesis director, and co-supervised by Dr. S. Van Petegem.- PhD student III on the microscopical analysis of dislocation structures, enrolled at the RWTH Aachen, faculty for metallurgy and materials technology with Prof. Dierk Raabe as first advisor, Prof. Gottstein as second advisor, and co-supervised by Dr. S. Sandlöbes.The aim of the proposal is to develop an experimentally validated computational method based on the crystal plasticity finite element (CPFE) method to simulate cyclic plastic deformation as occurs during low cycle fatigue in fcc materials. CPFE is an excellent computational tool that is depending on the constitutive input applicable for mechanical engineering issues as well as for the simulation of fundamental plasticity. Fatigue is a phenomenon of broad technological importance and poses a limit to the lifetime of components. A CPFE model of the cyclic plastic deformation occurring during low cycle fatigue is expected to elucidate the relation between the microstructural details (like the crystal orientation distribution) of the material and the process of crack initiation as part of fatigue.The uniqueness of the proposal is that it aims to develop a CPFE model for fatigue simulations with a constitutive input that is based on in-situ Laue experiments completed with electron back scatter diffraction (EBSD), electron channeling contrast imaging (ECCI) and transmission electron microscopy (TEM) analyses. The know-how required to accomplish this aim is only available by the combination of the expertise on fatigue held by the structural integrity group of the LNM (K. Janssens), the expertise held by the MSS (H. Van Swygenhoven and S. Van Petegem) necessary to perform in-situ Laue experiments and interpret these correctly, and the broad expertise of the MPIE (S. Sandlöbes) held on CPFE and the microscopy and diffraction methods used.
