Component-wise hyperreduction for nonlinear solid mechanics problems
Stephan Ritzert, Jannick Kehls, Erik Faust +3
Hyperreduced nonlinear solid-mechanics components can be generated offline and reused as transferable building blocks across different assemblies, boundary conditions, meshes, mate…
Multi-field decomposed hyper-reduced order modeling of damage-plasticity simulations
Jannick Kehls, Stephan Ritzert, Lars Breuer +3
This paper presents a multi-field decomposed approach for hyper-reduced order modeling to overcome the limitations of traditional model reduction techniques for gradient-extended d…
A unified multi-perspective quadratic manifold for mitigating the Kolmogorov barrier in multiphysics damage
Qinghua Zhang, Stephan Ritzert, Jian Zhang +3
In multiphysics damage problems, material degradation is often modeled using local or global damage variables, whose evolution introduces strong nonlinearities and significant comp…
A multi-field decomposed model order reduction approach for thermo-mechanically coupled gradient-extended damage simulations
Qinghua Zhang, Stephan Ritzert, Jian Zhang +3
Numerical simulations are crucial for comprehending how engineering structures behave under extreme conditions, particularly when dealing with thermo-mechanically coupled issues co…
Component based model order reduction with mortar tied contact for nonlinear quasi-static mechanical problems
Stephan Ritzert, Jannick Kehls, Stefanie Reese +1
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 w…
Modeling moving boundary value problems in electrochemical machining
Tim van der Velden, Stephan Ritzert, Stefanie Reese +1
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 fi…
