- Modern lightweight structures like satellites and wind turbine blades display non-linear stiffness. This key output of the £4.2M Engineering Nonlinearity Programme Grant (EP/K003836/1), built on author's previous work on backbone curves to develop a novel vibration-based method that delivers analytical models able to predict the dynamic response of nonlinear structures. Rigorous analytical, numerical and experimental work demonstrated the capabilities of the identification method. The method has been utilised by leading international groups (e.g. C. Ligeikis ligeikis@umich.edu, University of Michigan) studying the experimental validation of nonlinear structures and led to new international collaboration with the University of Wisconsin-Madison (M. Allen msallen@engr.wisc.edu).
