DOI: 10.1016/j.jsv.2017.11.048
Abstract: Abstract Different studies have demonstrated that vibration characteristics are sensitive to debonding in composite structures. Nevertheless, one of the main restrictions of vibration measurements is the number of degrees of freedom that can be acquired… read more here.

DOI: 10.1016/j.promfg.2018.02.063
Abstract: Abstract Vibrations lead to fatigue failure or damage which is harmful to engine supporting structures. The impact introduces large forces and thus large stresses, which can cause both vibrations and early failure of the mechanisms.… read more here.

DOI: 10.1016/j.soildyn.2020.106484
Abstract: Abstract We show how complex, three-dimensional modes of vibration of an irregular building can be identified by ambient vibration measurements. We present two-dimensional cross sections of the three-dimensional mode shapes and describe a measuring strategy… read more here.

DOI: 10.3390/en13061474
Abstract: Condition monitoring of gear-based mechanical systems in non-stationary operation conditions is in general very challenging. This issue is particularly important for wind energy technology because most of the modern wind turbines are geared and gearbox… read more here.
