• Mechanics of composites structures

Current Research

Real-time diagnostics for structural health monitoring necessitates the need for efficient environmental compensation strategies. Currently my research focus is to develop a model to compensate the effect of environmental temperature variation on ultrasonic guided waves for both metallic as well as composites structures.

Presently the model is capable of compensating the effect of change in ambient temperature on the piezoelectric transducer signals attached to the metallic structures using very minimal training data. This also provides an efficient tool for real-time state awareness of fly-by-feel autonomous vehicles using ultrasonic guided wave sensing.
