In particular, his descriptions of other researcher's findings related to rolling element bearing and eddy current induced Morton like phenomena are intriguing and of significant practical importance. Likewise, his description of prior work involving entrapped lubricant induced near...

.... Furthermore, it also states that rotor dynamic analysis generally fails to predict the potential existence of the Morton effect in the design stage or in a troubleshooting process. These issues are compounded by the fact that continuous fluctuation of vibration amplitude and phase angle prevents control...

... distribution, may cause intolerable synchronous vibrations that exhibit a hysteresis behavior with respect to rotor speed. First discovered by Morton in the 1970s and theoretically analyzed by Keogh and Morton in the 1990s, the ME is still not fully understood by industry and academia experts. Traditional...

The induced vibration phenomenon can be understood with the help of proper and detailed understanding of vapor bubble...

... Structures Vibration The refined formulations for thin elastic beams taking into account shear deformation and rotatory inertia are usually referred to as TBT. Analysis and development of this theory was the subject of numerous considerations. It could be argued that Timoshenko theory is not less...
