Structural health monitoring capabilities in ceramic–carbon nanocomposites

Structural Health Monitoring in Previous

The following text supports the lecture series AVT-220 on “Structural Health Monitoring of Military Vehicles” co-ordinated by STO-CSO. This lecture series is planned to run in Germany (BAM-Berlin) and Spain (Centro Convenciones MAPFRE –Madrid) during 2014, and Canada (Vancouver) in 2015. The author, Malcolm McGugan, is one of seven lecturers involved and this report accompanies his presentation...

Structural Health Monitoring

An experimental evaluation of the structural health monitoring capability of piezoelectric wafer active sensors on composite structures at cryogenic temperatures is presented. The piezoelectric wafer active sensor–based electromechanical impedance and the pitch–catch methods were first qualified for cryogenic temperatures using piezoelectric wafer active sensor–instrumented composite specimens ...

Wireless Monitoring Techniques for Structural Health Monitoring

Recently, a variety of wireless structural health monitoring systems have been demonstrated as viable substitutes for traditional high-cost tethered monitoring systems. In this study, a prototype wireless sensing system is deployed on the Voigt Bridge (La Jolla, CA) and a historical theatre (Detroit, MI) to validate its performance against cabled monitoring systems. Acceleration time history re...

Structural Control and Health Monitoring

A unique shape memory alloy (SMA) restrainer cable is developed and tested to evaluate its effectiveness in limiting the hinge opening in bridges. The SMA cables, connected at the deck–abutment interface, are tested on a four-span, one-quarter scale, concrete slab bridge. The bridge is subjected to a suite of ground motion to assess the performance of the SMAs under different magnitudes of load...
