Constitutive Theories for Polymers Using Non-Classical Continuum Mechanics
This thesis is on the development of a few constitutive theories characterising the thermo-mechanical response of polymers. In proposing the theories, some aspects of non-classical continuum mechanics are used. The first ... -
Constrained Adaptive Control of Nonlinear Systems with Application to Hypersonic Vehicles
Constraints in input, output, and states are evident in most of the practical systems. Explicitly incorporating these constraints into the control design process leads to its superior performance in general. Therefore, ... -
Constrained least squares finite element formulation of two-dimensional elastodynamic problems
In the present work, a least?squares finite element formulation for two?dimensional elastodynamic problems is developed. This development is based on an earlier formulation reported by Pratap. The earlier formulation was ... -
Constrained Optimal Guidance Design of Interceptors for High-Speed Ballistic Targets
In this thesis, optimal control theory has been applied to design constrained terminal guidance algorithms for interceptor to destroy incoming high speed ballistic targets. There exist several optimal guidance algorithms ... -
Constraining the Lithium Seawater Mass and Isotope Budget: Diagenetic Processes Through Marine Pore Waters
Silicate weathering consumes CO2 and controls cation fluxes to the ocean, thus playing a critical role in modulating long-term seawater chemistry and climate. There are very few markers of seawater chemistry whose value ... -
Constraint Effects On Stationary Crack Tip Fields In Ductile Single Crystals
(2011-03-15)In order to understand and predict the fracture behaviour of polycrystalline materials from a fundamental perspective, it is important to first investigate plastic deformation at a crack tip in a ductile single crystal. ... -
Construction of 3D CAD Models From 2D Orthographic Views
(2011-01-19)This thesis addresses the problem of constructing 3D CAD models from 2D engineering drawings of the object. Procedures for each step in the popular bottom-up approach are described. In each of the steps in this approach, ... -
Contact Line Instabilities in Thin Film Flows on Curved Surfaces
Thin fluid film flows are ubiquitous in nature and many industrial applications. Such flows are characterized by having the thickness in one direction being much smaller than the characteristic length scales in the ... -
Contact Mechanics Of Layered Structures
(2009-06-30)Contact mechanical study of layered structures is useful to various fields of engineering, such as - mechanical engineering, civil engineering, materials engineering and biomechanics. Thin hard film coating on a compliant ... -
Contaminant Transport through Soil and Effect of Bentonite and super-absorbent Polymer on Transport Parameters
(2018-08-20)The aim of this present research is to improve the containment properties of clayey soil by the use of bentonite and polymers as the additives. Clayey soils are generally used for the control of soil and water pollutions ... -
Contaminated Site Investigation and Remediation Using Modified Nano Zero Valent Iron Particles
Rapid industrialization has boosted economic growth but also increased contaminants in air, water, and soil. Improper disposal of municipal solid waste and industrial effluents has rendered many groundwater sources unfit ... -
A Continuous Optimization Approach To Protein Design With Structural And Functional Constraints
(2013-04-30)We have developed a novel computational approach to functional de novo protein design using gradient based continuous optimization techniques. Motivated by many engineering applications in which a cost function is optimized ... -
Continuous-Curvature Path Planning Using Four Parameter Logistic Curves
Autonomous vehicles perform time and cost effective operations with minimal or no human effort and hence, have the potential to be used in civilian, commercial and military applications. Pertaining to these applications, ... -
Continuum Analysis of Cavitation Induced Failure and Tensile Deformation Response of Metallic Glasses & Nanoglasses
Metallic glasses (MGs), which are metals solidified in an amorphous state, have shown attractive mechanical properties such as high strength (up to 5 GPa), yield strain (around 2%) and good corrosion resistance. They ... -
Continuum Modeling Of Adhesive Interaction Based On Interatomic Potentials
(2018-01-12)Adhesion between solid bodies plays a prominent role in a wide variety of situations ranging from tribological applications to dust coagulation initiating the formation of planets. It can be due to various reasons like ... -
Control and Safety of Multi-UAV Systems for Collaborative Payload Transportation and Target Tracking
Unmanned aerial vehicles (UAVs) have been widely used in reconnaissance, remote sensing, disaster relief, and agricultural applications. Many applications require multiple UAVs to cooperate to complete the assigned tasks. ... -
Control of Alternating Flow Phenomena in Transonic Shock Wave Boundary Layer Interactions Over Payload Region of a Generic Launch Vehicle Model
During the transonic phase of a launch vehicle’s ascent, aerodynamic loads peak due to high freestream dynamic pressure and angle of attack. In addition to steady loads, significant pressure fluctuations arise from Shock ... -
Control of shock-induced vortex breakdown in Transonic regime on a slender delta wing body configuration using blowing
Modern high speed aircrafts feature highly swept and low aspect ratio wings, mainly to increase the critical Mach number and reduce the wave drag. A special case of swept wings is wings with triangular planform commonly ... -
