Dr. Pal’s research is broadly in the area of solid mechanics and dynamics, investigating fundamental wave phenomena that arises from the interaction of geometry, anisotropy and material non-linearity with the objective of developing engineering applications.
Over the past few years, he has worked on mechanical meta-structures: artificially engineered structures with unique properties very distinct from their constituent materials. These unique/exotic physical properties arise as a consequence of shape, symmetry and non-linearity.
Dr. Pal’s expertise is primarily in continuum mechanics, wave propagation and computational mechanics.
The following pages have a brief description of Dr. Pal’s various research topics.
