The broad areas of Research are Simulation of Dislocations and Epitaxial systems by Finite Element Method, Study of complex intermetallics. Finite Element Method (FEM) is not only a powerful tool for engineering analyses, but also for understanding the fundamental material behavior at the nano scale. In fact 'new phenomenon' and 'new materials' can be discovered using FEM simulations. This becomes possible because continuum behavior can be retrieved at the length scale of even a few lattice spacing. Various structures and defects in crystals can be simulated and associated processes can be understood using FEM. These include:
- Simulation of dislocations, epitaxial films, twins, grain boundaries, precipitates etc.
- Study interactions between these defects
- Formation of interfacial misfit dislocations in epitaxial thin films
- Precipitation and coherent to semi-coherent transition of precipitates

Currently, we are developing micro-mechanics based models for the prediction and propagation of intralaminar damage mechanisms (like fibre breaking, fibre-matrix debonding, matrix cracking etc) along with interlaminar damage mechanism (delamination) for polymer matrix composite under quasi-static and dynamic loading. The model developed will be used to predict the fatigue life of composite structures. Measurement of fibre, matrix, lamina and laminate properties: We are also creating data bank for glass and carbon fibres mechanical and damage properties by single fibre tests. Similar properties are also measured for epoxy matrices. Further, effective mechanical and strength/damage properties are measured for various types of composites with above fibre/matrix systems. Adaptive finite element modeling: We are developing various plate models for laminate analysis to accurately predict the damage initiation and propagation until final fracture. The emphasis is to do a refined adaptive FE analysis for these damages with both discretization and modeling error estimation and control. Further, we model the damage mechanisms in commercial FEM software, Abaqus through UMAT subroutines.
