Journal of Sound and Vibration(2021)
Abstract
•Non-destructive measurement technique for magnetic-induced strain.•Development of an inverse dynamic model for magnetic strain identification.•Effect of the mechanical damping in electrical steels on the magnetic strain.•Distinction between the apparent strain and the magnetic-induced strain.•Effect of the non-linear magnetization on the mechanical response.
