The strain energy release rate (SERR) theory, combined with Linear Fracture Mechanics
and Rotordynamics theories, has been widely used over the last three decades in order to …

The harmonic balance (HB) method is widely used in the literature for analyzing the periodic
solutions of nonlinear mechanical systems. The objective of this paper is to exploit the …

Considering the parametric uncertainties, the model of a rotor system with transverse crack
is investigated. Polynomial Chaos Expansion is used to describe the uncertainties. The …

This paper focuses on the primary resonance analysis of a dual-rotor system having two
rotor unbalance excitations of different rotating speeds and being connected by an inter …

The actual breathing mechanism of the transverse breathing crack in the cracked rotor
system that appears due to the shaft weight is addressed here. As a result, the correct time …

We show how spectral submanifold (SSM) theory can be used to extract forced-response
curves without any numerical simulation in high-degree-of-freedom, periodically forced …

This study deals with the non-linear dynamic response of a flexible rotor supported by ball
bearings. The excitation is due to unbalance force. The finite element rotor system is …

By using the Duffing oscillator as a case study, this paper shows that the harmonic
components in the nonlinear system response to a sinusoidal input calculated using the …

This paper focuses on the nonlinear response characteristics of a dual-rotor system with a
breathing transverse crack in the hollow shaft of the high-pressure rotor (rotor 1). A finite …
