Craig-Bampton-based Quadratic Manifold for Nonlinear Substructuring
Alexander Saccani, Paolo Tiso
Component Mode Synthesis methods, such as the Craig-Bampton (CB) approach, are widely used in structural dynamics due to their modularity and compatibility with substructuring work…
AquaROM: shape optimization pipeline for soft swimmers using parametric reduced order models
Mathieu Dubied, Paolo Tiso, Robert K. Katzschmann
The efficient optimization of actuated soft structures, particularly under complex nonlinear forces, remains a critical challenge in advancing robotics. Simulations of nonlinear st…
Higher-order transmissibility and its linear approximation for in-service crack identification in train wheelset axles
Ehsan Naghizadeh, Eleni Chatzi, Paolo Tiso
In-service structural health monitoring is a so far rarely exploited, yet potent option for early-stage crack detection and identification in train wheelset axles. This procedure i…
A scalability benchmark study of model order reduction techniques for very large, strongly coupled vibroacoustic problems
Sander Metting van Rijn, Linus Taenzer, Paolo Tiso +1
Model Order Reduction (MOR) can significantly reduce the computational cost of vibroacoustic simulations. While most MOR research focuses on single-domain systems (e.g., structural…
Non-Intrusive Data-Free Parametric Reduced Order Model for Geometrically Nonlinear Structures
Alexander Saccani, Paolo Tiso
We present a fully non-intrusive parametric reduced-order modeling (PROM) framework for geometrically nonlinear structures subject to geometric variations. The method builds upon e…
Matching frequency response measurements and reduced order models for the inverse identification of viscoelastic properties
Linus Taenzer, Paolo Tiso, Bart Van Damme
3D-printed materials are used in many different industries (automotive, aviation, medicine, etc.). Most of these 3D-printed materials are based on ceramics or polymers whose mechan…
