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.

Our recent research is focused on three areas as listed below. Understanding the fracture behavior of materials in which there are property gradients. Currently we are looking at the effect of both elastic and toughness variation along the crack front on the stability of stationary cracks in layered systems. Both analytical and experimental techniques are employed to meet this objective. Subsequently the behavior of fast propagating cracks in these systems will be investigated. Observing in real-time the fracture processes at microscopic scale in polymers and make measurements of the local strain and displacement fields. This information will be used to develop models that can represent the fracture processes and eventually predict the fracture behavior of bulk polymers (with Dr. S. Basu). Investigate the effect of strain rate on the compressive strength and failure patterns of hard ceramics, when subjected to highly dynamic short duration loading (50-100 microseconds) using the Hopkinson bar technique combined with ultra high-speed imaging.

I work mostly in the area of nonlinear dynamics and control. Most of the applications are derived from engineering examples but some come from biology, ecology, economics as well as music. The work focuses on trying to unravel the fundamental unifying connections between the various examples of nonlinearities observed in nature. These diverse problems are modeled using various classes of functional differential equations like delay differential equations, fractional derivatives as well as partial or sometimes ordinary differential equations. The current emphasis is on understanding the natural dynamics of these systems so that they can be exploited in developing more efficient control systems.

We are in the process of developing a Microsystems fabrication laboratory and a team of researchers with the overall goal of being able to do cutting edge research in the areas of BioMEMS, Lab on a chip and Microfluidics based approaches to diagnose and detect clinical samples etc. We also evaluate the various Nano-technological approaches to synthesize smart materials which would be able to perform rapid sensing of gases, biological agents, physical parameters like temperature, pressure, explosions and combustion at the nanoscale with novel nanoenergetic materials etc. and interface these technologies with Microsystems. The vision of our research is to work in interdisciplinary areas of engineering and Life sciences and also to develop a team of researchers and workforce of the 21st century who can walk easily into a variety of domains of science and technology.
