Research

As an engineer, I focus on the application and use continuum mechanics to develop concepts to solve the problem or atleast progress in the area. While any physical phenomenon can be described through one or more partial differential equations (Navier-Stokes, Maxwell and so on), the physics of change (deformation, temperature change, fluctuations in electric / magnetic fields) in any matter is driven by the forces acting on them. In any particular application, we know the forces acting and need to determine the change or vice-versa. This general structure holds true when one considers all matter, from brain tissue to geology of the earth, through the scope of continuum mechanics. The overarching goal of my research is to explore and develop numerical methodologies for continuum (i.e. solid and fluid) mechanics aimed ot better understand interdisciplinary applications of scientific and societal importance.

My research, till date, can be broadly classified into the below themes:

  • Natural hazards engineering: With a focus on water-borne hazards
  • Nanotribology: With a focus on non-exhaust emissions
  • Aerospace structures: Using tensegrities and multifunctional composites

Natural hazards engineering

Natural hazards preparedness and sustainable hazard mitigation is critical to a nation’s ability to withstand and respond to natural disasters like earthquakes, tsunamis, hurricanes, tornado, wildfires and floods. They present a varied risk across any country. Just in the year 2020 (Jan – Jun), US has faced ten separate billion-dollar weather and climate-related disaster events as reported by the NOAA.

NOAA further estimates that the total losses in dollar amounts due to natural disasters is growing each year. Already, in 2020, the total estimated losses are greater than the average of the years of 1980 – 2020. This is already without accounting for the recent wildfires in California or the Atlantic hurricanes like Laura etc. Overall, over the last quarter-century, the natural hazards and the accompanying technological hazards have been dealt in with isolation. The birth of “hazards communities,” has brought together people from diverse fields and agencies to address the myriad aspects of natural disasters. Such dedicated efforts have helped reduce the resulting death, economic losses and vastly improved our understanding of the processes underlying natural hazards and the complexities of decision making, before and after a hazard. Over the last years, there has been a growing interest in addressing these natural hazards. Just in the US, the total funding in Million dollar amounts for study of natural Hazards is as shown.

My research focuses on using FEA and FVM for computational structural and fluid dynamics simulations to interface with empirical-driven models. This would ensure that the hazard analysis are based on more rational and scientific simulations and improve the trustworthiness of these results. This includes simulation of fluid (water / wind / air) flows, the building response due to fluid loading, impact between solid objects (or debris) and erosion of soil during events like tsunami and storm surges. Here, I aim to particularly study the impact of damage to ports and larger naval infrastructure due to impact of ships.
