Research Overview

My research objective is to study the elastic wave propagation through phononic materials and thereby design and develop smart materials for advanced engineering applications. Specifically, my research exploits the local geometric and nonlinear features to control global material response. In order to achieve this mission, I work in an interdisciplinary research environment where Structural Mechanics intersects with Elastic Wave Propagation and Nonlinear Dynamics.  Such an environment helps me:

  • Understand the effect of bulk materials and geometric configuration of architected materials on their quasi-static effective properties and bandgap characteristics
  • Understand how waves propagate and evolve in the presence of nonlinearity in phononic materials, and how we can control them.

Background: The world is looking for smart materials that are light yet durable, resistant to both static and dynamic loads, and energy-efficient. However, very few natural materials can meet these requirements. This opens up an opportunity to explore artificial materials intentionally architected in a specific geometric configuration over a wide range of length scales. Such materials (alternatively referred to as “lattice materials” or “phononic materials”) combines the parent material properties and geometric configuration to exhibit properties not observed in natural materials. Additionally, the incorporation of nonlinearity in these phononic materials results in nonlinear wave responses that have potential engineering applications in healthcare, safety, energy, and transportation in the form of vibration isolators, frequency filters, energy absorbers, cloaks, sensors, and superlenses.

Currently, I am a Ph.D. candidate in Mechanical Science and Engineering department and conduct research in the Wave Propagation and Metamaterials Lab with research advisor Dr. Kathryn H. Matlack. I study how elastic waves propagate and evolve through phononic materials and metamaterials. Specifically, my research makes use of finite element modeling, additive manufacturing, and experimental testing of architected materials to understand the fundamental mechanics of how wave interacts with complex structures.
