Analytical and Experimental Studies into Structural Health Monitoring

Abstract

The research objectives of this project were to develop a toolbox" of methods for monitoring the "health" of representative structural systems encountered in aerospace and aircraft structures subjected to arbitrary dynamic environments. The research was focused on developing methods suitable for use with structural response measurements from flexible structural components and assemblages that may incorporate elements undergoing significant nonlinear (i.e., not-necessarily-linear) deformations. Furthermore, the research developed innovative approaches for coping with the wide spectrum of situations arising in the aircraft and aerospace field. It did this by formulating a general approach for using structural vibration measurements to analyze and quantify the extent and location of relatively small changes in the structural parameters, which may be precursors of serious damage to the structure being monitored.
