A variety of rotating machines are associated with almost everyone’s life. It includes small handheld devices to large industrial applications such as sewing machine, fan, motor cycle, car, commercial vehicles, railways, steel industries, power plants, sugar industries, turbines, and space shuttles. A rotating machine comprises several machine elements. The healthy operation of rotating machine is closely allied with the functioning of other linked machine elements. Therefore, diagnosing the fault at the early stage and performing prognosis accordingly are always of prime importance.

The objectives of this special issue are to explore the most recent methodologies of analysis and provide deep insight into the fault diagnosis and prognosis to the upcoming generation. This special issue invites the original research articles, having significant contribution in modelling, experiments, and their combination. Review articles related to fault diagnosis and prognosis are also encouraged.

Potential topics include, but are not limited to:

• Health monitoring
• Fault diagnosis and detection
• Reliability and uncertainty
• Nonlinear analysis
• Physics of failure
• Prognostics and health management
• Remaining useful life prediction and life assessment
• Development of faults and their effects with maturity
• Developments of defects and their correlation with diagnosis and prognosis
• New designs and developments
• Applications of various techniques such as vibration, sound, and current signature
• Wear modeling and analysis
• Tribological analysis
