Nanoengineered composites for damage detection and load monitoring of mechanical and aerospace systems

Interdisciplinary Areas: Engineering and Healthcare/Medicine/Biology

Project Description

This project will explore the design and fabrication of nanoengineered composite materials and their application to multiphysics tomographic imaging for damage detection and load monitoring. Structural Health Monitoring (SHM) systems have the potential to revolutionize the life cycle and the maintenance approach of a wide spectrum of mechanical systems by drastically increasing their safety, reliability, and sustainability. The current maintenance approach is based on “pre-scheduled” operations that do not account for the actual status of the structural component. Despite much progress in the SHM field in recent years, almost none of the most advanced SHM technologies have yet made the transition to real-world applications. When considering composite materials the applications are even fewer. This project will explore the concurrent design of novel composite materials and monitoring systems in order to develop composite structural systems exhibiting unprecedented monitoring and self-assessment functionalities. 
The postdoctoral researcher will perform theoretical, numerical, and experimental work at the interface between continuum mechanics, imaging and inverse problems, and material fabrication. The selected candidate will utilize the state of the art facilities at Purdue’s TNT Laboratory, Structural Health Monitoring and Dynamics Laboratory, and Ray W. Herrick Laboratories in order to perform computations, material fabrication, and experiments.
