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 Reduced Order Model for Joint Assemblies by Hyper-Reduction and Model-Driven Sampling
Ahmed Amr Morsy, Mariella Kast, Paolo Tiso
The dynamic behavior of jointed assemblies exhibiting friction nonlinearities features amplitude-dependent dissipation and stiffness. To develop numerical simulations for predictiv…
An enhanced parametric nonlinear reduced order model for imperfect structures using Neumann expansion
Jacopo Marconi, Paolo Tiso, Davide E. Quadrelli +1
We present an enhanced version of the parametric nonlinear reduced order model for shape imperfections in structural dynamics we studied in a previous work [1]. The model is comput…
Model Order Reduction for Temperature-Dependent Nonlinear Mechanical Systems: A Multiple Scales Approach
Shobhit Jain, Paolo Tiso
The thermal dynamics in thermo-mechanical systems exhibits a much slower time scale compared to the structural dynamics. In this work, we use the method of multiple scales to reduc…
Hyper-reduction over nonlinear manifolds for large nonlinear mechanical systems
Shobhit Jain, Paolo Tiso
Common trends in model order reduction of large nonlinear finite-element-discretized systems involve the introduction of a linear mapping into a reduced set of unknowns, followed b…
Generalization of Quadratic Manifolds for Reduced Order Modeling of Nonlinear Structural Dynamics
J. B. Rutzmoser, D. J. Rixen, P. Tiso +1
In this paper, a generalization of a quadratic manifold approach for the reduction of geometrically nonlinear structural dynamics problems is presented. This generalization is cons…
A Quadratic Manifold for Model Order Reduction of Nonlinear Structural Dynamics
Shobhit Jain, Paolo Tiso, Daniel J. Rixen +1
This paper describes the use of a quadratic manifold for the model order reduction of structural dynamics problems featuring geometric nonlinearities. The manifold is tangent to a…
