Reductions in natural frequency are often used as a damage indicator for
structural health monitoring (SHM) purposes. However, fluctuations in
operational and environmental conditions, changes in boundary conditions, and
slight differences among nominally-identical structures can also affect
stiffness, producing frequency changes that mimic or mask damage. This
variability has limited the practical implementation and generalisation of SHM
technologies. The aim of this work is to investigate the effects of normal
variation, and to identify methods that account for the resulting …
