Report

Modeling moving boundary value problems in electrochemical machining

Autor: van der Velden, Tim, Ritzert, Stephan, Reese, Stefanie, Waimann, Johanna

Publikováno v: Int. J. Numer. Methods Eng. (2023)

This work presents a new approach to efficiently model the cathode in the moving boundary value problem of electrochemical machining. Until recently, the process simulation with finite elements had the drawback of remeshing required by the changing s

Report

A geometrically adapted reduced set of frequencies for a FFT-based microstructure simulation

Autor: Gierden, Christian, Waimann, Johanna, Svendsen, Bob, Reese, Stefanie

We present a modified model order reduction (MOR) technique for the FFT-based simulation of composite microstructures. It utilizes the earlier introduced MOR technique (Kochmann et al. [2019]), which is based on solving the Lippmann-Schwinger equatio

Report

A novel approach for the efficient modeling of material dissolution in electrochemical machining

Autor: van der Velden, Tim, Rommes, Bob, Klink, Andreas, Reese, Stefanie, Waimann, Johanna

Publikováno v: Int. J. Solids Struct. 229 (2021) 111106

This work presents a novel approach to efficiently model anodic dissolution in electrochemical machining. Earlier modeling approaches employ a strict space discretization of the anodic surface that is associated with a remeshing procedure at every ti
