DOI: 10.1016/j.ijfatigue.2020.105912
Abstract: Abstract Turbine bladed disks normally operate under complex loadings coupling with uncertainties originate from multiple sources, including material variability, load variation and geometrical uncertainty. The influence of these uncertainties on mechanical response of engineering components… read more here.

DOI: 10.1016/j.ymssp.2021.107917
Abstract: Abstract Turbine bladed disks with friction contacts may have a large scattering of dynamic response amplitudes in laboratory conditions even for two consecutive tests. The non-repeatability of experimental studies might directly be related to a… read more here.
