What is SHM?
Structural Health Monitoring (SHM) is the continuous or regular monitoring of the condition of a structure or
system using built-in or autonomous sensory systems, and any resultant intervention to preserve structural integrity. SHM is a broad multidisciplinary field both in terms of the diverse science and technology involved as well as in its varied applications. The technological developments necessary to enable practical structural
health monitoring are originating from scientists and engineers in many fields including physics, chemistry, materials science, biology, and mechanical, aerospace, civil and electrical engineering. SHM is being implemented on diverse systems and structures such as aircraft, spacecraft, ships, helicopters, automobiles, bridges, buildings, civil infrastructure, power generating plants, pipelines, electronic systems, manufacturing and processing facilities, biological systems, and for the protection of the environment, and for defense.
