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 …

Damages in rotor systems have severe impact on their functionality, safety, running
durability and their industrial productivity, which usually leads to unavoidable economical …

Vibration monitoring is one of the primary techniques of condition monitoring of rotating
machines. Shaft misalignment and rotor unbalance are the main sources of vibration in …

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 …

Over the decades, vibration-based condition monitoring has become well accepted and
widely used to identify faults in rotating machines. However, the quantification of faults may …

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 …

In the structural health monitoring field, damage detection has been commonly carried out
based on the structural model and the engineering features related to the model. However …

This paper presents a model-based transverse crack identification method suitable for
industrial machines. The method is validated by experimental results obtained on a large …

The purpose of this paper is to investigate the use of the 2× and 3× super-harmonic
frequency components for detecting the presence of a single transverse breathing crack in a …

The identification of a transverse crack on a beam is the subject of many investigators.
Identifying the crack means to find its position and depth. In many cases there are more than …
