Feasibility study of structural damage detection using NARMAX modelling and Nonlinear Output Frequency Response Function based analysis
The work is one of the two central ideas underpinning the £1.17M EPSRC NEWTON grant (EP/J012343/1). The Nonlinear Output Frequency Response Function (NOFRF), established by Lang and Billings, has resolved the decades-old problem of nonlinear frequency domain analysis. This study develops a pioneering time domain modelling and NOFRF-based frequency domain analysis method for damage diagnosis of nonlinear structural systems. The method resolves many fundamental problems with existing techniques, and has potential to provide revolutionary solutions to damage diagnosis for example railway and nuclear power plant infrastructures.
