Special Finite elements for analysis of pain jionts in composite plates
Joints are essential to connect various components of a structural assembly. Among various methods of joining, pin (or fastener) joints are of detachable type and are the most preferred under situations requiring periodic ... -
Investigation of cutting mechanisms and strain fields during orthogonal cutting in CFRPs
Cutting mechanisms in fiber reinforced plastics (FRPs) have been studied in the present work. Full field strains are measured using the digital image correlation (DIC) technique, and force signals are measured using a ... -
Finite element analysis of stress concentrations and singularities
Stress concentrations or singularities occur in a structure whenever there is a sharp change in geometry, or discontinuities in loading or material properties. In the analysis of problems with significant concentrations, ... -
Study of large scale unstable air sea interactions in the tropics using a coupled ocean atmosphere model
Coupling between the ocean and the atmosphere plays an important role in determining the nature of short-term climate fluctuations in the tropics, such as the El Niño–Southern Oscillation (ENSO). Although the tropical ocean ... -
Role of ozone in sun weather relationships
This thesis comprises analytical studies of the relationships between solar/geomagnetic activity and the day-to-day variation of total atmospheric ozone at five selected stations — Resolute, Churchill, Hohenpeissenberg, ... -
Sensitivity studies on the structure of the monsoon desert heat flow.
The sensitivity of the atmospheric response to large-scale summer continental sensible heat sources, such as those prevailing over the great deserts of the Afro-Asian landmass, is studied in this thesis. Understanding this ... -
Effects of solar and geomagnetic activity on stratospheric temperatures
This thesis comprises analytical investigations of temperature variations in the 21–60 km altitude region related to solar and geomagnetic activity. The analyses have been carried out using Meteorological Rocket Network ... -
Studies on effects of solar and geomagnetic activity on mesospheric temperature
This thesis comprises analytical and experimental investigations of the mesosphere, specifically the altitude region 50–90 km. The analytical work consists of correlation analyses of mesospheric temperature data from ... -
On High-Speed Curved Compression Ramp Air Intakes
A scramjet, i.e., a supersonic combustion ramjet, is an air-breathing engine that enables sustained atmospheric flight in the hypersonic regime. It consists broadly of four key components: the air intake, isolator, combustor, ... -
Compressive behavior of continuous fiber polymer composites in the presence of process-induced defects
The current work examines how process-induced defects influence the compressive behavior of composite structures. The defects analyzed include wrinkles at the macroscale and fiber misalignment at the microscale. ... -
Multi-Agent Coordination using Convex Formations and Binary Tree Structures
Multi-agent systems are increasingly deployed in missions involving large-scale tasks with complex objectives that are beyond the capability of a single agent. Such missions demand computationally efficient coordination ... -
Elastic Wave Propagation in Textured Polycrystalline Media
The performance and reliability of structural components in advanced engineering applications, such as turbine discs in aeroengines, are critically influenced by their microstructural characteristics, particularly the ... -
Development of Optimal Distributed Resource Utilisation Approaches Under Connectivity Constraints for Energy Internet
The global transition to sustainable power generation has driven a rapid increase in Distributed Energy Resources (DERs), especially from renewable sources. When integrated with energy storage, these localised generation ... -
Nonlinear mode theory of shear flow development
The major part of this thesis is concerned with the description of a new technique for analysing the development of shear layers (particularly in free flows). A principal feature of this method is the expansion of the ... -
On the migration of maximum tropical rain fall zone in a simple climate model
The aim of this thesis is to understand the seasonal migration of the maximum precipitation zone in the tropics (ITCZ) using a simple climate model. An attempt is also made to extract at least phenomenological answers to ... -
Effect of convex transverse surface curvature on transition and other properties of incompressible boundary layer.
A study of the incompressible boundary layer with transverse surface curvature has been made with particular reference to transition from laminar to turbulent flow. Calculations based on linearised hydrodynamic stability ... -
Elastic Wave Dispersion Analysis and Mode Shape Investigation of Higher order Beam Theory for Thick Beams
The dynamic behavior of structural components, particularly thick beams, is critical in many engineering applications, including aerospace engineering, civil infrastructure, and mechanical systems. The rigid cross-section ... -
On The Theory of burning of monopropellant droplets
This thesis is concerned with theoretical investigations on some aspects of monopropellant droplet combustion. The burning characteristics have been obtained by solving the governing differential equations which are ... -
Some experimental investigations of the fine scale structure of turbulence
In this thesis some properties of the fine scale structure have been investigated experimentally. The terminology “fine scale structure” means, in the author's opinion, small eddies which are different from energy?containing ...
