The main purpose of the present review paper is to illustrate the principal achievements of
numerous researchers who have studied the non-linear effects caused by a closing crack in …

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 purpose of this book is to give a basic understanding of rotor dynamics phenomena with
the help of simple rotor models and subsequently, the modern analysis methods for real life …

Rotor crack occurs frequently in rotating machinery. It is of great significance to study the
vibration mechanisms of the cracked rotor-bearing system, which can provide proofs for …

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 …

This paper presents a novel way to detect fatigue transverse cracks in rotating shafts. The
proposed detection methodology exploits both the typical nonlinear breathing phenomenon …

In this paper, a new method based on high-precision modal parameter identification method
and wavelet finite element (WFE) model is presented to determine the depth and location of …

The article introduces a new mathematical model for the cracked rotating shaft. The model is
based on the rigid finite element (RFE) method, which has previously been successfully …

A finite element model of a rotor with slant crack is presented. Based on fracture mechanics,
a new flexibility matrix for the slant crack is derived that accounts for the additional stress …

A simple Jeffcott rotor model of a rotor with a slant crack is presented. Flexibility matrix of the
rotor with slant crack is developed and the stiffness coefficients based on the flexibility …
