Abstract:

Condition evaluation of large-scale structures, termed mesoscale structures
(e.g. civil, aerospace, and energy structures) is difficult due to their
large size and complex geometries. Additionally, there exists a lack of
economic and scalable sensing technologies that are capable of detecting,
localizing, and quantifying local faults over a structures global area. A
solution to this local-global problem is the deployment of an inexpensive
dense sensor network that is capable of detecting and localizing damage
over a structure’s global area.

This work will present advancements in two such dense sensor networks. The
first consists of a sensing skin developed from a flexible capacitor that
is mounted externally onto the structure. When deployed in a dense sensor
network configuration, these large area sensors are capable of covering
large surfaces at low cost and can monitor both strain- and crack-induced
damages. The second sensing technology consists of smart-cementitious
material doped with multi-wall carbon nanotubes, which has been
demonstrated to be suitable for monitoring its own deformations (strain)
and damage state (cracks). Integrated into a structure, this smart
cementitious material can be used for detecting damage or strain through
the monitoring of its electrical properties.
Presenter: Austin Downey is an assistant professor at the University of
South Carolina in the Department of Mechanical Engineering. His research
focuses on increasing the resiliency of mesoscale structures to both
manmade and natural events through the real-time monitoring, modeling, and
adaptive control of structures. He has authored over 20 journal papers
related to his research and is the lead inventor on two U.S. patents. He
obtained his PhD from Iowa State University in 2018 in Engineering
Mechanics and Wind Energy Science, Engineering, and Policy, where he was an
NSF-IGERT fellow.
