My work focused on using Ultrasonic Additive Manufacturing, a solid state, low temperature welding method to nondestructively embed FBG sensors into aluminum for in-situ measurement of aerospace structures/devices. After demonstrating that the process was feasible for blank optical fiber, a significant amount of work was done demonstrating that the measurements themselves were accurate, precise, and repeatable when compared to other sensing elements.
