Biography

Dr. Susanta Ghosh worked as an Associate in Research in the Pratt School of Engineering at the Duke University. He was a postdoctoral scholar at the Departments of Aerospace Engineering and Materials Science & Engineering at the University of Michigan, Ann Arbor. Prior to joining University of Michigan he was a research fellow at the Technical University of Catalunya, Barcelona, Spain. His M.S. and Ph.D. degrees are from the Indian Institute of Science (IISc), Bangalore, and BS degree from Indian Institute of Engineering Science and Technology, Shibpur.

His research interest lies in the broad area of Multi-scale Solid Mechanics, Atomistic Modeling, Ultrasound Imaging, Inverse Problem and Computational Science.

  • Computational Inverse Problem:  Computational inverse problem for material characterization of soft biological tissues from ultrasound data. 
  • Phase Filed Crystal (PFC) modeling: PFC modeling to study elastic and inelastic deformation in a wide variety of non-equilibrium phenomena at microscopic length scales and on diffusive time scale.

Multi-scale modeling:

  • Graphene materials and carbon nanotubes:  Development of computationally efficient atomistic-continuum models for multilayer graphene materials and carbon nanotubes at engineering scales by combining nonlinear mechanics with homogenization and multiscale techniques.
  • Nonlocal elasticity of epoxy with atomistic kernel:  Nonlocal elasticity based length-scale coupling through molecular dynamics (MD) simulations of polymeric materials with the aim of improving composite performance for aerospace applications;
  • Computational solid mechanics:  Nonlocal elastic modeling. Efficient and objective finite-element implementations for Geometrically exact (nonlinear) beam and shell theory. Eigen analysis of transfer matrix for representative unit cell to characterize mechanics of repetitive structures.
  • Integration algorithms: Development of integration algorithms for strongly nonlinear oscillators by incorporating analytical techniques in numerical algorithms. Development of accurate integration algorithms for rotational dynamics with short-term quasi-stability properties.
  • Probabilistic methods: Probabilistic seismic risk assessment. Probabilistic modeling of microstructure evolution for polycrystals using orientation correlation function.
