Matrix cracking in polymer matrix composites under static and fatigue loading
Matrix cracking is the first and most dominant mode of damage in polymer matrix composite (PMC) laminates resulting in significant stiffness degradation under static and fatigue loading. Matrix crack evolution and its ... -
Modelling and optimization of novel therapies for HIV and hepatitis C virus infections
Curing infections by HIV and hepatitis C virus (HCV) have remained a challenge for a long time due to their efficient ways of evading host immune responses and therapies. They do so by rapidly mutating their genomes, which ... -
Uncertainty modeling and analysis of aerospace structures
Aerospace structures are different from other structures due to the difference in the required properties for an aerospace application. The primary motivation of this kind of structure lies in its lightweight nature, ... -
Simulation and Study of Noise Generated due to Turbulent Boundary Layer in Towed Hydrophone Array
In this thesis, a wave propagation based analytical model is developed for an underwater towed array. The towed array is modeled as an in finite tube filled with a certain liquid and submerged in an in finite volume of ... -
Synthesis, Microstructural Stability and High Temperature Deformation of Alumina-Carbon Nanotube Composites
Structural ceramics such as alumina are known to have excellent hardness and high temperature mechanical properties. In view of this, they are used as refractory linings to mitigate the effect of high temperature exposure. ... -
Impact of Local and Remote Land-Atmosphere Coupling on the Indian Summer Monsoon
India lies on the edge of the Asian summer monsoon domain and receives almost 80% of its annual rainfall during June to September (referred as Indian summer monsoon rainfall: ISMR). The dominant forcing behind inter-annual ... -
Analyzing Inter-modal Competition Between High Speed Rail and Conventional Transport Modes in Indian Context
Indian Railway provides an important mode of public transport in India. This is the most commonly used and cost effective long-distance transport system of the country. Indian Railways has played an immense role in ... -
Discrete Velocity Boltzmann Schemes for Inviscid Compressible Flows
It is known that high-speed flows are compressible. In large parts of the flow domains, the inviscid approximation is valid and this leads to Euler equations of gas dynamics. These inviscid compressible flows are modelled ... -
On the Contribution of the Launch Platform towards Acoustic Environment of a Launch Vehicle at Lift-off
A launch vehicle experiences intense acoustic loading in the initial phase of its lift-off due to the noise generated by the rocket exhaust. This affects the launch vehicle structure in addition to sensitive payloads and ... -
Design and Analysis of Multifunctional Composites for Unmanned Aerial Vehicles
The principal aim of this thesis is to analyse the effectiveness of multifunctional composites as intelligent structures to improve mechanical properties and activate additional non-structural features. In order to investigate ... -
Aeroelasticity of Flapping Wings towards Micro Air Vehicle Applications
Studies have revealed that insect like flapping flight can serve as a benchmark in designing Micro Aerial Vehicles (MAV) owing to its power efficiency and high maneuverability. Primarily envisioned as agents facilitating ... -
Investigations on Miniature Loop Heat Pipe with Flat Evaporator
The present investigation on a miniature loop heat pipe (LHP) with flat evaporator is motivated by two factors. Firstly, miniature loop heat pipes are required for thermal management of small electronics in spacecraft with ... -
Blast Effects on Mild Steel Plates and Blast Mitigation using Fluid-filled Polymer Foam
In the modern-day society, there are an increasing number of explosions, either by accidental explosions or by terrorist attacks on civilian and military infrastructure. In view of the increased threat to infrastructure ... -
Novel Phenomena Associated With Giant Tetragonality in the Ferroelectric BiFeO3-PbTiO3 System
The multiferroic perovskite solid solution xBiFeO3-(1-x)PbTiO3 (BF-PT) exhibits very unique features such as giant tetragonality (c/a ~ 1.19), coexistence of ferroelectric and magnetic order (in certain composition range) ... -
Organic-Inorganic Hybrid Photovoltaics : Interface Engineering, Fabrication and Characterization
In the past few decades the field of organic electronics particularly organics photovoltaic (OPVs) find wide interest among researchers. It finds many advantages such as light weight, low temperature fabrication requirements, ... -
Design and Development of a Novel Solar Thermal Receiver
One of the most widely used solar collectors for process heating and large scale electricity generation is the parabolic trough collector (PTC), in which a tube placed at the focus of the parabola receives concentrated ... -
Vertical Structure of Convective Clouds Using the TRMM PR Data
Very small fractional area (0.1%) occupied by the cumulonimbus (Cb) clouds belies their importance in Earths hydrological cycle and climate. For example, Riehl and Malkus (1958) estimated that the vertical transport of ... -
Multiscale Simulations in Multiphase Flows
Matter at small scales is not a continuum. Whenever we are dealing with phenomena which have disparate time and length scales, we have to rely on multiscale modelling approach in order to capture the complete physics. A ... -
Applications of Advanced CAE Methodologies to Orthopaedic Implant and Vehicle Occupant cum Pedestrian Safety Countermeasure Design
In the present work, experimental and numerical investigations into the load-displacement responses of a human lumbar Truncated Vertebral Unit (TVU) under quasi-static and impact loading conditions have been carried out ... -
An Integrative Approach to Vision Simulations using Digital Human Models
Digital Human Models (DHM), belong to a class of human-in-the-loop simulations having primary applications in the area of virtual ergonomics, virtual prototyping, and task evaluations. These models replicate physical and ...
