STRUCTURAL HEALTH MONITORING (SHM)


PEC sponsored short course on Structural Health Monitoring (SHM) is being conducted to familiarize engineers with latest trends in Non Destructive Evaluation (NDE) methods for monitoring and ensuring structural integrity. It has extensive application in aerospace, mechanical and civil engineering. SHM is a system with the ability to detect and interpret adverse “changes” in a structure in order to improve reliability and reduce life cycle costs.

In SHM, structures are continuously monitored during their use by embedded or attached Non Destructive Evaluation sensors. SHM is being used extensively in structural integrity and structural life enhancement programs in aviation industry.

For aircraft applications, the use of SHM technologies for future aircraft will not only enable new possibilities for maintenance concepts but will have a significant influence on design concepts and assembling technologies. SHM is expected to be one of the key technologies for controlling the structural integrity of future aircraft, providing both maintenance and weight saving benefits. Some of the advantages over conventional NDE inspection include reduced inspection down time, elimination of component tear down, and potential prevention of failure during operation. SHM is likely to be used in identifying failures in aircraft, which would also be a boon to the commercial aircraft industry.​


Learning Objectives & Benefits​

This course has been designed to familiarize engineering officers with modern trends and techniques available for structural health monitoring of aerospace structures. The importance of this course for PAF can be appreciated from the fact that one of the major problems faced by PAF is life cycle prediction and management of aged fleet. The main contents of this course included theory of structural analysis covering aircraft loading, low cycle/high cycle fatigue and modern computational techniques. Besides this advanced areas like use of sensors to monitor structural failures have also covered in this course.​
