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 …

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 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 …

The advanced phase of the breathing crack in the heavy duty horizontal rotor system is
expected to be dominated by the open crack state rather than the breathing state after a …

The effect of crack depth of a rotor-bearing-disk system on vibration amplitudes and whirl
orbit shapes is investigated through a general harmonic balance technique and …

Fatigue damage, appearing due to developing cracks, is considered to be one of the main
faults in rotating machinery. The damage in rotating components can be catastrophic, posing …

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

By analyzing the limitations of weight dominance and by taking the complicated whirl of the
rotor into account, general equations of motion have been developed in case of a Jeffcott …

The dynamic stability of dynamical systems with time-periodic stiffness is addressed here.
Cracked rotor systems with time-periodic stiffness are well-known examples of such …

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 …
