Developing Parametrically Homogenized Continuum Damage Mechanics (PHCDM) Model for Composite materials. This PHCDM model accounts for the microscopic morphology and evolution of composite materials during the analysis of macroscopic deformation and damage. Meanwhile, the multi-scale damage model is much more computationally efficient than the conventional FE2 methods, enabling us to understand material failure behaviors across multiple length scales with affordable computation resource.

Integrated Image-Based Multi-Scale Modeling of Yield, Creep, and Fatigue in Nickel-Based Superalloys

My current research is focused on the development and integration of statistical characterization of nickel-based superalloys. Recently we have developed a method of generating statistically equivalent virtual microstructures, and establishing domains for which the microstructural and property response volumes converge. My current focus is in developing a probabilistic crack nucleation model as a function of material state variables.

Area of work

I am interested in multiscale damage modeling of composites material. Now I am working on the parametrically homogenized continuum damage mechanics (PHCDM) model for woven composites materials. We use the PHCDM model to predict damage behavior across various composites material length scales. The three-dimension representative volume element RVE of woven composites is used to predict the micro mechanical properties. The effective material properties of woven composites are studied using the numerical homogenization techniques to get the micro-macro equivalence embedded in PHCDM model.


Saikat Dan

Area of work:

I am currently working on multiphysics problems. My work essentially encompasses coupled mechanical and electromagnetic systems used in antenna and sensor applications. Specifically, I am in the process of developing material models for piezoelectric sensors to be used in the quantification of material damage in mechanical systems. I work with and develop finite element programs for solving coupled electromagnetics (Maxwell’s Equations of Electromagnetics) and mechanics (Equations of Mechanical Equilibrium) in a finite deformation paradigm. This facilitates in solving more complex mechanical systems involving sensing of mechanical damage from evolving electromagnetic fields.

My work is focused on computational modelling of multifunctional materials, in which the material behavior is governed by more than one governing equations and follows a coupled constitutive law. Currently, I am working on developing an efficient finite element model for piezoelectric materials in finite deformation framework by establishing a two-way coupling between mechanical and transient electric fields.
