Report

Component based model order reduction with mortar tied contact for nonlinear quasi-static mechanical problems

Autor: Ritzert, Stephan, Kehls, Jannick, Reese, Stefanie, Brepols, Tim

In this work, we present a model order reduction technique for nonlinear structures assembled from components.The reduced order model is constructed by reducing the substructures with proper orthogonal decomposition and connecting them by a mortar-ti

Report

A multi-field decomposed model order reduction approach for thermo-mechanically coupled gradient-extended damage simulations

Autor: Zhang, Qinghua, Ritzert, Stephan, Zhang, Jian, Kehls, Jannick, Reese, Stefanie, Brepols, Tim

Numerical simulations are crucial for comprehending how engineering structures behave under extreme conditions, particularly when dealing with thermo-mechanically coupled issues compounded by damage-induced material softening. However, such simulatio

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
