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…

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…

Accelerating Construction of Non-Intrusive Nonlinear Structural Dynamics Reduced Order Models through Hyperreduction
Alexander Saccani, Paolo Tiso
We present a novel technique to significantly reduce the offline cost associated to non-intrusive nonlinear tensors identification in reduced order models (ROMs) of geometrically n…
