Research Interests: 

Nakshatrala's general research interest includes mathematical formulation and analysis, and development of computational techniques for problems in structural, solid, and fluid mechanics. His current research interests include degradation/healing of man-made and natural materials, and heterogeneous porous media (both flow and structural aspects).

Nakshatrala's application areas include degradation/healing of civil and aerospace structures and materials, geosciences (contaminant transport, carbon-dioxide sequestration, enhanced oil recovery) and bio-mechanics. The research goal is to develop relevant mechanics, numerical techniques, and mathematical tools to model and study various (steady state and transient) multiscale phenomena. Specific research topics of interest include:

Geomechanics

  • Flow and transport in deformable porous media
  • Constitutive modeling of geomaterials
  • Fracturable porous media

Computational Mechanics

  • Multiscale and stabilized finite elements
  • Coupled problems, structure-structure interaction, fluid-structure interaction
  • Numerical homogenization and upscaling techniques
  • Numerical optimization and sensitivity analysis
  • Applications and numerical techniques for differential-algebraic equations (DAEs)

Continuum Physics

  • Modeling degradation / healing of materials and structures
  • Nonlinear continuum mechanics
  • Thermomechanical constitutive modeling & Implicit constitutive modeling
  • Theory of interacting continua

Applied Mathematics and High Performance Computing

  • Partial Differential Equations (More of a spectator)
  • Maximum Principles
  • Applied Optimization
  • Parallel Computing
