(2017-11-16)Indian cities are currently facing various transportation issues like congestion, pollution, urban inequity, high fatality rate due to accidents etc. because of an increase in the ownership of private motor vehicles and ... -
A Non Resonant Piezoelectric Sensor for Mass, Force and Stiffness Measurements
(2018-09-04)The word piezo in greek means \to compress". Piezoelectric sensors work on the principle of direct piezoelectric effect, where a mechanical input generates a corresponding electric charge. The advantages of these sensors ... -
Non-catalytic synthesis of biodiesel and solubilities of mixtures of lipid derivatives in supercritical fluids
The fossil fuels are depleting rapidly as the demand for energy and its allied chemicals is continuously increasing in the modern world. In addition, the concerns over climate change due to the greenhouse gases emitting ... -
Non-catalytic Synthesis of Biolubricant Esters and their Solubilities in Supercritical Fluids
Breakdown products released due to increased loss of mineral oil based lubricants to the environment lead to aquatic toxicity and release of harmful volatile compounds into the atmosphere. The production of these conventional ... -
A non-classical continuum approach to study the fragmentation of brittle solids
In this thesis, a non-local continuum approach coupled with the phase-field theory and Jones-Wilkins-Lee (JWL) equation of state (EOS) is proposed to model and simulate blast-induced fracture in brittle materials. Also, ... -
Non-classical continuum models for solids using peridynamics and gauge theory
This thesis focuses on three areas of nonclassical continuum mechanics of solids. In the first part, we develop a few peridynamics (PD) models and solution strategies for discretized PD equations in the context of the ... -
Non-classical mechanics and thermodynamics for continuum modelling of solids
This thesis dwells upon several aspects of continuum mechanics and thermodynamics to model elastic and inelastic response of solids. Broadly, the work presented may be categorized into two parts{ one focusing on the ... -
Non-Dimensional Kinetoelastic Maps for Nonlinear Behavior of Compliant Suspensions
(2018-02-18)Compliant suspensions are often used in micromechanical devices and precision mechanisms as substitutes for kinematic joints. While their small-displacement behavior is easily captured in simple formulae, large-displacement ... -
