A non-classical continuum approach to study the fragmentation of brittle solids
In this thesis, a non-local continuum approach coupled with the phase-field theory and Jones-Wilkins-Lee (JWL) equation of state (EOS) is proposed to model and simulate blast-induced fracture in brittle materials. Also, ... -
Monitoring and Control of Intermittent Water Distribution Network
Millions of people in low and middle-income countries worldwide receive water only for a small fraction of the time in a day through piped networks. Even though the percentage of the world’s population with access to piped ... -
Understanding Catchment Scale Processes: Hydrological Modelling and Information-Theoretic Approaches
Catchments are complex environmental systems, and they serve as the fundamental units for hydrological classification. They are self-organizing systems whose form, drainage network, ground and channel slopes, channel ... -
Efficient Finite Element-Based Approaches for Solving Potential Flow Problems in Fluids
For many years, fluid flows have been modeled, starting from basic potential flow equations to full Navier-Stokes equations. The complexity of the flow increases as viscous effects, boundary layer, and flow separation are ... -
Classical Approach to Understanding the Impact Dynamics of Hollow Droplets
Compound droplets are utilized in applications ranging from the preparation of emulsion to biological cell printing and additive manufacturing. Here, we report on the impact dynamics of a compound hollow droplet on a ... -
On late stages of transition in round jets
A round jet is one of the simplest canonical axisymmetric free shear flows that occur both in engineering applications and natural phenomena. A laminar-turbulent transition process is inherent to its development involving ... -
An Experimental Investigation of Transitional and Turbulent Channel Flow
This thesis is a comprehensive experimental investigation of transitional and turbulent channel flow in the Reynolds number range of Reτ = 55 − 1559. Towards this objective, a new channel flow facility was designed and ... -
Approaches to Regional Analysis of Hydro-Meteorological Processes and Extremes
Regional analysis of hydrometeorological variables (e.g., evapotranspiration, precipitation), hydrological processes (e.g., runoff), and their extremes (e.g., drought, floods) is essential for various applications. The ... -
PDMS-Based Nanocomposite for EMI Shielding application
Lightweight, flexible, and easy-to-integrate solutions are in great demand in electronic devices. The present work deals with the preparation of Poly dimethyl siloxane (PDMS) based nanocomposite for suppressing electromagnetic ... -
Probabilistic design and optimization of foundations on cohesionless soil using surrogate models
The design of foundations depends on the properties of soil, which are affected by various forms of uncertainties. These uncertainties affect the foundation performance and hence are considered in the deterministic design ... -
Development and Studies of Open-Pore Metal Foam for Diverse Applications
This thesis presents a method for producing open-cell metal foams by vibration-assisted casting (VAC) and its studies for diverse engineering applications. Metal foams have a wide range of applications due to their several ... -
Extraction of Equivalent Uniaxial Plastic and Viscoplastic Behavior from Bending Using a Mechanistic Approach
The present work is aimed at the extraction of material’s yield and creep parameters using cantilevers by conducting constant deflection rate and constant load tests respectively. Under the assumption of Euler-Bernoulli’s ... -
Modelling spatial and non-spatial conflicts across multiple design domains
This thesis aims to detect spatial and non-spatial conflicts in product design arising out of requirements in different design domains. Handling such conflicts requires modelling the non-geometric knowledge outside the ... -
Multi-linear Disassembly Path Determination: A Geometric Approach
This thesis presents a geometric approach for determining the orientation-preserving disassembly paths of polyhedral assembly components. Exact disassembly path determination of the components is essential because the ... -
Posturing for Autonomous Digital Human Model
Digital Human Models (DHMs) are representations of humans in virtual environments that have applications in diverse disciplines. In the context of engineering design, DHMs are used to assess if a proposed design satisfies ... -
Inkjet-Printed Co-continuous Mesoporous Oxides for Surface Dominated Functional Devices
Over the last few decades, printed and flexible electronics have emerged as a major area of research, which may cater multiple domains of application requirements for the forthcoming industrial revolution. The solution ... -
Stirring and mixing driven by mesoscale eddies in the stratified Bay of Bengal
The stirring of passive tracers driven by altimetry-derived daily surface geostrophic currents is studied on subseasonal timescales in the Bay of Bengal. Advection of latitudinal and longitudinal bands highlights the chaotic ... -
