We at Autonomous Mini Helicopter Lab are interested in comprehensive rotorcraft analysis, prediction of helicopter blade loads in severe maneuvers, inverse flight dynamics simulation, which involves the estimation of control angles to simulate a particular maneuver. Further we are involved in design and analysis of hover capable rotary wing Micro Air Vehicles and UAVs. We are also fascinated with Unconventional VTOL/STOL systems, variable speed helicopters and wind turbines.

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.

The interfacial properties, in particular interfacial adhesion and interfacial fracture toughness govern the mechanical integrity of thin film devices, inevitably subjected to repeated thermo mechanical loading while in operation. The laser spallation method proves better than contemporary interfacial strength characterization techniques due to its ability to dynamically load the interface in non-contacting fashion by employing short duration laser induced stress pulses (at strain rate ~ 107). The laser spallation setup will be installed to measure tensile and mixed-mode interfacial strength in thin film specimens, fabricated using polymer, low-k, metallic and ceramic films. The reliability testing and analysis will be conducted on multilayer thin film equipments such as solar cells, microelectronics devices, and MEMS and NEMS devices.

The theory of homogenization is, in a nut-shell, the asymptotic analysis of a system. A layman motivation towards homogenization can be given from the material science point of view. It is a mathematical concept that incorporates the study of the macroscopic behaviour of a composite medium through its microscopic properties. The known and unknown quantities in the study of physical or mechanical processes in a medium with microstructure depend on a small parameter $\varepsilon = \frac{l}{L}$, where $L$ is the macroscopic scale length of the dimension of a specimen of the medium and $l$ is the characteristic length of the medium configuration. The study of the limit, as $\varepsilon\rightarrow 0$, is the aim of the mathematical theory of homogenization. The case $\varepsilon\rightarrow 0$ is important as a tool for numerical computations. Over the time, the theory of homogenization has found application in various branches. One of them being Shape optimization. Simply put, one may be interested in finding the optimal shape of a body that will have, for instance, maximal conductivity, rigidity etc. All these physical problems end up as a PDE with rapidly oscillation coefficients.
