Experimental, Numerical and Probabilistic Analysis of Reinforced Anchors for Transmission Tower Foundations
The foundations of tall structures such as transmission towers are subjected to loads in three directions coming from wind and other environmental events. The use of anchors for application in transmission tower foundations ... -
Wave Propagation in Bio-inspired Inhomogeneous Waveguides for Impact Mitigation Applications
Decades of research aim to shield structures and people from impact and shock, mitigating damage and traumatic brain injuries. The development of novel structures to absorb energy and reduce stress waves in structures ... -
Bearings-Only Quadrotor Guidance in Gap Traversal Scenarios
In autonomous missions, quadrotors are often required to safely fly through gaps or openings. Designing traversal guidance strategies becomes crucial in such scenarios, especially when the quadrotor relies on the information ... -
Studies on Flexural Fatigue Behaviour of Plain Concrete – Mechanisms of Crack Growth, Effect of Loading Amplitude, Frequency and Notch Size
Concrete structures such as bridges, pavements and off shore structures are subjected to fluctuating loading throughout their service life. These fluctuating loads cause progressive internal damage to structures leading ... -
Comparison of Additive and Multiplicative Kinematics in Large Deformation Plasticity
The most widely used plasticity model in commercial finite element analysis software packages is the additive plasticity model. One of the more well-known alternatives to additive plasticity is multiplicative plasticity. ... -
Simulation of complex plastic flows in metal sliding and cutting
Metal manufacturing encompasses a broad range of mechanical transformation processes that shape native metal into useful forms. These processes generally involve the interaction of a hard tool with a specimen / workpiece, ... -
Dynamics of Leidenfrost droplets on microtextured substrates
A liquid droplet placed on a heated substrate at temperatures significantly higher than the saturation temperature of the liquid levitates over a thin film of vapor and is termed as a Leidenfrost (LF) droplet. Leidenfrost ... -
Understanding design communication in internet-enabled remote synchronous collaborative design in the early stages of design
Remote synchronous collaborative design necessitates designers to carry out the design process using web-based real-time communication applications for collaboration with co-designers. Design communication involves exchanging ... -
Revisiting the General Circulation of the Tropics
This thesis examines some aspects of the tropical general circulation. First, we consider the zonal momentum budget of the tropical upper troposphere. Our motivation is the zonal inhomogeneity of the Earth that presents ... -
Multi-component Gas Mixture Separation: Fundamental Studies to Pilot Scale Development and Characterization
Climate change has become one of the significant challenges of the 21st century resulting in increased demand for low-carbon energy carriers to achieve a sustainable future. Thermo-chemical conversion of environmentally ... -
Arabian Sea High Salinity Core in the Bay of Bengal
The Summer Monsoon Current (SMC) advects high salinity water from the Arabian Sea into the Bay of Bengal (BoB) during the summer monsoon. This high salinity water subducts and enters the BoB as a subsurface high salinity ... -
Effects of 3d Morphological Characteristics of Sand on Multi-scale Intergranular and Sand-geosynthetic Interactions
To understand the process of mobilization of shear strength in sands and sand-geosynthetic interfaces at a fundamental level, it is essential to precisely characterize the size and shape of the grains and the shear-induced ... -
Morphological Perspectives of Sand Liquefaction and its Mitigation
Liquefaction of soils under seismic conditions has profound implications for infrastructure resilience in earthquake-prone regions. Saturated loose cohesionless granular soils have the tendency to readily lose grain contacts ... -
Investigating and Modelling the Microscopic Pedestrian Behavioral Dynamics in Mass Religious Gatherings
Pedestrian models that can realistically reproduce observed pedestrian movement dynamics are crucial in facility planning and pre-event planning of crowded situations. Despite the elaborate arrangements, crowd disasters ... -
Exploration of Design Thinking in School Education
This thesis comprehensively investigates the integration of design thinking into education, focusing on its application in K-12 settings in India. The broad aims of the research work are: 1. To investigate the need to ... -
Micromechanics of Wedge and Cone Indentation of Metallic Specimens with Subsurface Voids
Near-surface voids and pores occur in metal parts manufactured by processes as diverse as casting, powder metallurgy, and additive manufacturing. These pores range in size from a few microns to a few mm, depending on the ... -
Platinum overlayers characterization and fabrication via self-terminating electrodeposition
Hydrogen is considered a promising alternative fuel for the future. However, despite its perception as a “zero-carbon” energy carrier, fossil fuels remain the primary feedstocks for hydrogen production, involving significant ... -
Interfacial oscillations and atomization of liquid jets from non-circular orifices
Understanding the flow behaviour of liquid jets discharging from orifices is essential for several applications such as fuel spraying, ink-jet printing, aerosol devices in pharmaceutical industries, micro-machined fuel ... -
Paper-Based Point-of-Care Diagnostic Tools: Electrokinetic Nucleic Acid Extraction and Saliva-Based Glucose Detection for Diabetes Monitoring
Currently, we face a global challenge posed by the dual burden of chronic diseases such as diabetes and infectious diseases such as tuberculosis (TB). Low-and middle-income countries are disproportionately overburdened by ... -
Low–Speed Impact Mechanics and Fragmentation of Wooden Panels: Characterization of Indian Woods
Low–speed impact (LSI) of brittle structural panels by rigid bodies causes significant damage, evident in familiar scenarios like the breaking of monolithic and laminated glass panes due to stone pelting, punching a hole ...
