Research Overview

My research objective is to study the elastic wave propagation through architected materials and thereby design and develop lightweight multifunctional metamaterials. In order to achieve this mission, I work in an interdisciplinary research environment where Material Science intersects with Elastic Wave Propagation and Additive Manufacturing.  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 through architected materials and how we can control them.
  • Realize manufacturing challenges and possible solutions to make architected materials feasible for real-world applications

 

Background: The world is looking for lighter yet durable materials to improve energy efficiency. Structures that are multifunctional – capable of exhibiting better mechanical, thermal, electrical and optical properties – are the need of our society. 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 “lattices”, “phononics” or “metamaterials”) combines the material properties and geometric configuration to exhibit properties not observed in natural materials.

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 metamaterials.  My research makes use of finite element modeling, additive manufacturing, and experimental testing of multifunctional metamaterials. The metamaterials I design can be potentially used in acoustic, structural and biomedical applications as vibration isolators, frequency filters, energy absorbers, cloaks, sensors, and superlenses.
