Structural Health Monitoring of Composite Structures

Abstract

Structural Health Monitoring (SHM) aims at evaluation of structural performance by regularly monitoring various physical parameters captured by a network of sensors. In-service SHM plays a significant role, especially in composite structures, where a majority of damages are invisible and inaccessible. In this article, the recent research and development work carried out in the field of sensors and instrumentation for SHM applications and damage detection algorithms have been critically reviewed. Implementation of SHM strategy on various composite structures has also been discussed.
