Quantum-Continuum Modeling and Simulations of Semiconductor Nanostructures
This thesis proposes a multi-physics model to couple the electrical, mechanical, thermal and quantum mechanical interactions in semiconductor and their heterostructures. Governing differential equations and constitutive ...
On the Contribution of the Launch Platform towards Acoustic Environment of a Launch Vehicle at Lift-off
A launch vehicle experiences intense acoustic loading in the initial phase of its lift-off due to the noise generated by the rocket exhaust. This affects the launch vehicle structure in addition to sensitive payloads and ...
Aeroelasticity of Flapping Wings towards Micro Air Vehicle Applications
Studies have revealed that insect like flapping flight can serve as a benchmark in designing Micro Aerial Vehicles (MAV) owing to its power efficiency and high maneuverability. Primarily envisioned as agents facilitating ...
Discrete Velocity Boltzmann Schemes for Inviscid Compressible Flows
It is known that high-speed flows are compressible. In large parts of the flow domains, the inviscid approximation is valid and this leads to Euler equations of gas dynamics. These inviscid compressible flows are modelled ...
Characterization of Cure Residual Strain in CFRPs
Fiber reinforced plastic (FRP) structures are widely used compared to metallic structures due to their superior mechanical properties and lightweight. However, anisotropy and heterogeneity inherent to FRPs cause a multitude ...
Analysis of Kinematic Constraints in Fixed-Wing UAV Formation Flying
Rise in autonomy has led to increase in usage of Unmanned Aerial Vehicles (UAVs) for various applications and has allowed the UAVs to perform complex and hazardous missions with ease. Formation of multiple UAVs finds ...
Ionic Polymer Metal Composite Actuators for Insect Scale Flapping Wing Micro Air Vehicle
Flapping wing micro air vehicles (MAV) have broad applications such as exploration
