 Beyond offering an independent estimation – particularly valuable when frequency measurements are challenging – the numerical model can also be used for the optimization of the experimental process. Overall, this methodology has the potential for real-time monitoring and strength prognosis of vibrating structures, such as aircraft wings or wind turbine blades, given the availability of vibration signal measurements and consideration of population and operational uncertainties. The next phase of this research involves scaling up the estimation process to structural components. References Pantelakis, S.
