Experimental and numerical study of mechanics and mechanisms of mode I fracture of a textured magnesium alloy
In recent years, magnesium alloys have gained increasing application in the automotive industry to achieve weight reduction in vehicle components which is crucial for enhancing fuel efficiency and meeting stringent emission ... -
Understanding the interplay between immune response and virus evolution
RNA viruses are the underlying cause of many human diseases, including the common cold, influenza, dengue fever, and COVID-19. Their ability to evolve rapidly makes them challenging to tackle, resulting in public health ... -
Studies on Metal Hydride Based Multifunctional Coupled Thermal Battery Systems
Thermal energy storage systems (TESS) based on chemisorption/thermochemical reactions have several advantages over conventional thermal storage systems based on sensible and latent heat. The advantages include high energy ... -
Tropical Teleconnections to the Indian Summer Monsoon in Observations and in a Coupled Model
An accurate seasonal prediction of Indian summer monsoon rainfall (ISMR) holds immense importance for the socio-economic well-being of South-Asian countries, as it directly impacts agricultural output and overall economies. ... -
Response of Granular Materials Towards Blast Loading
Granular media, such as sand, soil, and rocks, are commonly encountered in various engineering and geotechnical applications, and their response to blast loading is of significant interest. In this master’s thesis, the ... -
Exploring End-of-Life Photovoltaic (PV) Panel as a Building Material: A Case of Crystalline Silicon PV
The renewable energy share in the energy mix worldwide is rising sharply to mitigate climate change, with Solar Photovoltaics (PV) carrying a large share of 3.6%. However, the end-of-life (EoL) management of decommissioned ... -
Computational study of membrane driven secondary structural changes in proteins
Conformational changes in proteins, the most abundant biomolecule found in all living organisms, are ubiquitous and triggered by several factors essential for protein function. Protein conformational changes typically occur ... -
Discrete Velocity Boltzmann Schemes with Efficient Multidimensional Models
Traditional CFD algorithms have achieved a high degree of sophistication for modelling fluid flows in the past five decades. This sophistication can be seen clearly in one dimensional modelling, with a wide variety of ... -
Computational analysis of polymer nanocomposites across length scales
Polymer nanocomposites (PNC) exhibit excellent mechanical properties making them a promising material for several engineering applications. The enhancement in properties is primarily attributed to the toughening and ... -
Accurate Prediction of Enhancement Factors for Water Flow Through Boron Nitride Nanotubes
Water in nanoconfined spaces, such as nanotubes, exhibit anomalous yet intriguing behaviour compared to bulk water, a better understanding of which can enable us to realize a sustainable future. Nanotubes are atomically ... -
Formulations for solving geomechanics stability problems using stress characteristics and finite element limit analysis with power type and Mohr-Coulomb yield criteria
In geotechnical engineering, the stability analysis is often carried out to determine the ultimate collapse load that a geo-structure can possibly withstand. The accurate prediction of the exact collapse load is often very ... -
Comprehensive Investigation of the Mechanical Behavior of Nial-x (X=pt, Pd) Alloys: Effect of Composition, Orientation and Temperature
Gas turbine engines in the turbine section operate at temperatures exceeding 1300°C, which can cause high-temperature oxidation and reduce the lifespan of turbine blades. To counter this, thermal barrier coating (TBC) ... -
Towards metal additive manufacturing using alternate powders
Metal powders are predominantly produced using processes derived from atomization, which, apart from being highly energy intensive, are also inflexible and very material specific. These limitations are particularly acute ... -
Climate-resilience of Dwellings in Transition and the Thermal Behaviour of their Inhabitants
Thermal comfort is critical for the well-being, and productivity of the inhabitants. Traditional dwellings constructed using local, low-carbon materials have for decades provided comfortable indoor thermal environment to ... -
Synergistic Effect of Electromagnetic Forces on the Failure of Pre-Cracked Thin Metallic Conductors
Finite element method (FEM) simulations were performed, and distributions of current density, electromagnetic force, and stress fields due to the self induced electromagnetic forces were evaluated in a pre-cracked thin ... -
Precambrian ocean, life, and syn to post-collisional records in the Himalayas (Kumaun)
The Ph.D. thesis focuses on the central sector of the Himalayas, i.e., Kumaun. Here, an attempt has been made to understand the poorly understood genesis of magnesium carbonates (sparry magnesite) of the Precambrian ... -
Fracture and Fatigue Behaviour of Notched Plain Concrete Beams: The Role of Theory of Critical Distances and Acoustic Emission
Concrete structures, including buildings, bridges, pavements, and offshore structures, face a wide range of loading conditions, both static and cyclic. When subjected to fatigue loading, the response of concrete elements ... -
Stress-Assisted Pitting Corrosion Studies in Metallic Structures Using Advanced Modeling Methodologies
Pitting corrosion poses a significant threat to deepwater oil and gas production facilities, yet our current understanding of its impact on specific systems such as steel catenary riser (SCR), tensioned leg platforms (TLP), ... -
