Development of a Model Order Reduced Arbitrary Lagrangian Eulerian (MORALE) formulation for structures subjected to dynamic moving loads
Atul Anantheswar, Jannick Kehls, Ines Wollny +3
In recent developments, it has been demonstrated that the Arbitrary Lagrangian Eulerian (ALE) formulation can be utilized to improve computational efficiency, when simulating the r…
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…
Reduced-order structure-property linkages for stochastic metamaterials
Hooman Danesh, Maruthi Annamaraju, Tim Brepols +2
The capabilities of additive manufacturing have facilitated the design and production of mechanical metamaterials with diverse unit cell geometries. Establishing linkages between t…
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…
