Abstract: The mechanical damage state monitoring technology combines a variety of monitoring and detection methods and advanced sensor technology to extract material deformation, creep, cracks, spalling and other damage information during machine operation in real time or on a regular basis, so as to grasp the health status of the equipment in time, so as to ensure the efficient operation of the equipment. Reasonable planning of maintenance timing and effective avoidance of accidents is an important technical support in the field of mechanical equipment fault diagnosis and intelligent operation and maintenance. The damage monitoring process based on smart materials and smart structures has the characteristics of fast response, accurate quantification, and precise positioning. It meets the new needs of health monitoring for the development of complex mechanical structures, mechatronics, intelligent control, and continuous operation. The new direction of the development of equipment health detection technology. This article introduces the structure and principle of typical damage monitoring smart materials, reviews the research progress of condition monitoring smart materials for major damage modes such as mechanical wear, fatigue and corrosion, and points out the future development focus of damage monitoring smart materials.
