Abstract

The switching crack model having two different stiffnesses, depending upon the crack status, is developed. The necessary conditions for the crack opening/closing states are then analytically derived from a simple rotor with a switching crack. The validity of the switching crack model and the crack opening/closing conditions is proved through numerical simulations and experiments, and a crack identification scheme based on the analysis is also proposed.
