Non-intrusive reduced order modeling of dynamical systems with large stochastic dimensions
The work done in this thesis falls under the broad category of computational mechanics. This thesis addresses the computational challenge of high-dimensional regression and interpolation within the framework of a proper ... -
Non-Linear Finite Element Analysis Using Strain-Space Plasticity Coupled With Damage
(2011-01-27)The Thesis deals with Strain-Space Plasticity and its implementation in Nonlinear Finite Element frame-work coupled with damage. Conventional Stress-Space Plasticity, though very popular amongst commercial nonlinear FEM ... -
Non-linear Vibration of Beam Immersed in Fluid
In space launch vehicles with liquid propulsion system, various sub-systems like gas bottles, anti-slosh baffles and fluid lines are placed inside the propellant tanks which become partially filled over time during flight. ... -
Non-Local Continuum Models for Damage in Solids and Delamination of Composites
The focus of the thesis is on developing new damage models for brittle materials and using these to study delamination of composite structures. Chapter 1 gives an introductory literature review in order to motivate the ... -
Nonequilibrium wake flows
In order to study the memory of the larger eddies in turbulent shear flow, experiments have been conducted on plane turbulent wakes subjected to external pressure gradients. In some of these experiments the pressure gradient ... -
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 ... -

Nonlocal continuum models for plasticity and damage
Nonlocal interactions of material points play a vital role in modelling certain important aspects of inelastic phenomena such as plasticity and damage in solids. For plasticity problems, nonlocal interactions allow ... -
Novel Compression Fracture Specimens And Analysis of Photoelastic Isotropic Points
(2017-10-11)Compression fracture specimens are ideally suited for miniaturization down to tens of microns. Fracture testing of thermal barrier coatings, ceramics and glasses are also best accomplished under compression or indentation. ... -
A Novel Energy Neutrality Framework for Effective Integration of Energy-saving Sensors in Buildings
Buildings consume more than 40% of the primary energy produced globally, making them the leading contributors to climate change and global warming. Effectively reducing building energy is essential to reduce its energy ... -
Novel Finite Element Formulations For Dynamics Of Acoustic Fluids
(2013-05-02)Fluid-structure interaction (FSI) as the name suggests, is the study of dynamic interaction of both fluid and structure motions. Fluid-structure interaction exists in almost all engineering and science fields. Moreover, ... -
A Novel Hybrid Vehicle Architecture : Modeling, Simulation and Experiments
(2018-05-22)Electric and hybrid vehicles are particularly suited for use in urban areas since city transportation is mainly characterized by relatively short driving distances, low continuous power requirements, long idling times and ... -
Novel L12 precipitate hardened Co-base alloys
Conventional cobalt base superalloys relied on solid-solution and carbide precipitate based strengthening. They lacked high temperature (more than 800 ˚C) creep strength as compared to Ni-base superalloys which are ... -
Novel Manufacturing Technique of Metal Foams by Mechanical Processing of Hollow Spheres
Aluminium foams have high specific strength and higher stiffness than other contemporary packaging materials. They have important application as packaging material for critical applications that needs highest safety ... -
Novel Microfluidic Tools for Multiplex Colorimetric Detection of Analytes and Point Mutation Detection in Infectious Pathogens
Recently, the need for affordable point-of-care tests has grown exponentially. An ideal point of care (POC) test or device should satisfy the WHO-endorsed ASSURED criteria, meaning that the test/device should be accessible, ... -
