DOI: 10.1016/j.ymssp.2018.03.039
Abstract: Abstract Given a structure in a state with any type of perturbation, the steady-state vibrational response will be identical to that in the unperturbed state if the perturbation is rendered dormant and, of course, if… read more here.

DOI: 10.1016/j.ymssp.2018.11.012
Abstract: Abstract Modal curvatures have been claimed to contain local information on damage and to be less sensitive to environmental variables than natural frequencies. However, simply using the difference between modal curvatures in the undamaged and… read more here.
