This thesis focuses on three areas of nonclassical continuum mechanics of solids. In the first part, we develop a few peridynamics (PD) models and solution strategies for discretized PD equations in the context of the ...

Directionally solidified Nickel-based superalloys are the workhorse for the Jet Engine turbine rotor blades and nozzle guide vanes (NGV) applications. Su 247LC DS is the material used for turbine rotor blades and NGVs of ...

Clouds exist on all scales from turbulent processes to global scale and are organized on all the scales in between. They truly are multi-scale in nature. This makes them a very challenging simulation problem for atmospheric ...

Flapping wing micro air vehicles (MAV) have broad applications such as exploration in hazardous environment, reconnaissance, search and rescue. Ionic polymer metal composites (IPMC) have emerged as a promising material ...

This thesis deals with the development of guidance laws for interceptors with seeker field-of-view (FOV) and impact angle constraints. Two classes of guidance problems, namely, field-of- view and impact angle constrained ...

An experimental study on the rheology and kinematics of dense granular materials is presented in this thesis in the slow flow regime. In this study, we employ an often used experimental set up of the cylindrical Couette ...

Munitions like projectiles and artillery mortars follow ballistic trajectory to hit the target. However, unguided munitions may miss the target due to external disturbances or errors in aerodynamic modeling. A guided ...

Terrestrial ecosystems play an important role in the global carbon cycle by naturally taking up carbon from the atmosphere through photosynthesis and storing this carbon as biomass and soil carbon. There exists a strong, ...

The mechanics of fracture evolution in heterogeneous material like concrete is a distinct and complex phenomenon and still stands as an open problem after decades of research. A cluster of multi-scale cracks ahead of the ...

HIV infects around 1 million people every year. Antiretroviral therapy (ART) is used to suppress viral replication and control disease progression but it cannot eradicate the virus. ART is therefore lifelong. Today, e ...
