Over the past two decades, integrated Structural Health Management (SHM) systems have attracted considerable attention within the aerospace, marine, and civil engineering industries. The general aim of SHM systems is to increase structural safety and reduce maintenance cost by way of real-time monitoring of structural response and failure due to actual service loads including harsh and extreme environments. Traditional non-destructive techniques are costly, time-consuming, and commonly have limited utility; for these reasons, they are generally impractical for real-time response assessment in large, complex structural assemblies.

This mini-symposium will focus on recent advances in computational methods and tools for practical application to Structural Health Management systems. Abstracts discussing forward and inverse formulations that couple experimental measurements with computational mechanics models and that are aimed at real-time response and damage identification in metallic and laminated composite structures are of interest. In addition, novel and efficient approaches based on forward and/or inverse formulations incorporating large amounts of measured data from networks of bonded or embedded sensors are of interest. Further, approaches that enable shape- and stress-sensing capabilities, i.e., reconstruction of the deformed structural shape and stress distribution from measured discrete strain data are of interest. Methods which estimate applied loads such as impact forces and aerodynamic pressure using real-time experimental measurements are of interest. Abstracts are sought in the field of actuation and control systems for operating smart structures such as morphing wings or conformal antennas. Such structures require real-time shape sensing to provide feedback to the actuation and control systems. Theoretical developments, computational approaches, and coupled experimental-computational research studies are also within the scope of this mini-symposium.
