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 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 …

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

Timely detection of fatigue cracks is necessary to avoid catastrophic failure of rotating
machines which can lead to economical losses and accidental risk. This paper presents an …

The vibration monitoring of the rotating machines is an effective tool to detect rotating
element's defects at their early stages. The dynamic characteristics such as natural …

The breathing mechanism of cracks in rotating shafts is accurately investigated by means of
3D non-linear models. The behaviour is then modelled by means of a much simpler …

Fatigue crack is an important rotor fault, which can lead to catastrophic failure if undetected
properly and in time. Study and Investigation of dynamics of cracked shafts are continuing …

The vibration problems associated with geared systems have been the focus of research in
recent years. As the torque is mainly transmitted by the geared system, a slant crack is more …

Propagating fatigue cracks can have detrimental effects on the reliability of the rotating
machinery such as turbomachinery, process machinery, etc. Dynamic analysis of cracked …
