Locating isolas in nonlinear oscillator systems using uncertainty quantification
Dongxiao Hong, David A. W. Barton, Simon A. Neild
Parametric uncertainty in nonlinear dynamical systems can fundamentally alter bifurcation behaviour, leading to qualitative response changes. Predicting operating margins/envelopes…
Iterative method for real-time Hybrid testing: application to a cantilever beam with two interface degrees of freedom
Alessandra Vizzaccaro, Sandor Beregi, David A. W. Barton +1
In this paper, an iterative method for real-time hybrid testing (RTHT) is proposed. The method seeks to iteratively balance the interface conditions between the physical and numeri…
Real-time hybrid testing using iterative control for periodic oscillations
Sandor Beregi, David A. W. Barton, Djamel Rezgui +1
Real-time hybrid testing is a method in which a substructure of the system is realised experimentally and the rest numerically. The two parts interact in real time to emulate the d…
Using scientific machine learning for experimental bifurcation analysis of dynamic systems
Sandor Beregi, David A. W. Barton, Djamel Rezgui +1
Augmenting mechanistic ordinary differential equation (ODE) models with machine-learnable structures is an novel approach to create highly accurate, low-dimensional models of engin…
Robustness of nonlinear parameter identification in presence of process noise using control-based continuation
Sandor Beregi, David A. W. Barton, Djamel Rezgui +1
In this study, we consider the experimentally-obtained, periodically-forced response of a nonlinear structure in the presence of process noise. Control-based continuation is used t…
Numerical Continuation in Nonlinear Experiments using Local Gaussian Process Regression
L. Renson, J. Sieber, D. A. W. Barton +2
Control-based continuation (CBC) is a general and systematic method to probe the dynamics of nonlinear experiments. In this paper, CBC is combined with a novel continuation algorit…
Application of control-based continuation to a nonlinear structure with harmonically coupled modes
L. Renson, A. D. Shaw, D. A. W. Barton +1
This paper presents a systematic method for exploring the nonlinear dynamics of multi-degree-of-freedom (MDOF) physical experiments. To illustrate the power of this method, known a…
On the Geometrically Exact Low Order Modelling of a Flexible Beam: Formulation and Numerical Tests
C. Howcroft, R. G. Cook, S. A. Neild +3
This paper proposes a low order geometrically exact flexible beam formulation based on the utilisation of generic beam shape functions to approximate distributed kinematic properti…
Force appropriation of nonlinear structures
L. Renson, T. L. Hill, D. A. Ehrhardt +2
Nonlinear normal modes (NNMs) are widely used as a tool for developing mathematical models of nonlinear structures and understanding their dynamics. NNMs can be identified experime…
Experimental continuation of periodic orbits through a fold
J. Sieber, A. Gonzalez-Buelga, S. A. Neild +2
We present a continuation method that enables one to track or continue branches of periodic orbits directly in an experiment when a parameter is changed. A control-based setup in c…
