Generalized Circular and Elliptical Honeycomb Structures/Bundled Tubes : Effective Transverse Elastic Moduli
(2018-01-01)Omnipresence of heterogeneity is conspicuous in all creations of nature. Heterogeneity manifests itself in many forms at different scales, both in time and space. Engineering domain being an exotic fusion of human creativity ... -
Generation, Characterization and Control of Nanoscale Surface Roughness
(2018-01-11)Surface roughness exists at many length scales-from atomic dimensions to meters. At sub-micron scale, the distribution of roughness is largely dependent on the process that generates the surface through the mechanisms of ... -
Geometric And Material Stability Criteria For Material Models In Hyperelasticity
(2013-07-17)In the literature, there are various material models proposed so as to model the constitutive behavior of hyperelastic materials for example, St. Venant-Kirchho_ model, Mooney-Rivlin model etc. The stability of such material ... -
Geometric Reasoning with Mesh-based Shape Representation in Product Development
(2017-10-09)Triangle meshes have become an increasingly popular shape representation. Given the ease of standardization it allows and the proliferation of devices (scanners, range images ) that capture and output shape information as ... -
Growth And Characterization of ZnO Nanostructures for Device Applications : Field Emission, Memristor And Gas Sensors
(2017-11-09)Zinc oxide (ZnO) is perhaps one of the most widely studied material in the last two decades. It has received so much of attention because of its incredible potential for wide ranging applications. ZnO is a wide band gap ... -
Gust Rejection in Insect Flight
Large commercial and military aircraft can fly in turbulent wind conditions except in extreme weather events like cyclones. Smaller man-made vehicles like Micro aerial vehicles (MAVs) and Nano aerial vehicles (NAVs) are ... -
A Haptic Simulator for Gastrointestinal Endoscopy : Design Development and Experiments
(2018-09-04)Endoscopy is an involved clinical practice requiring considerable skill in performing the procedure. Virtual reality together with haptics offers immersive, flexible, and cost-effective platform for training in endoscopic ... -
Heat Transfer and Visualization Studies in the Evaporator of a Flat Loop Heat pipe
Heat pipes are extensively used in spacecraft thermal control and electronics cooling for transfer of heat from high heat flux zones to low heat flux zones. The major advantage of heat pipe is it can transfer high heat ... -
Heterogeneous Object Modelling : Representation, Construction and Process Planning
(2018-06-26)Heterogeneous Objects are engineered with multiple materials to achieve multiple functionalities like high hardness, high toughness and low structural weight. Heterogeneous objects are increasingly used to achieve multiple ... -
High Reynolds Number Flow Over A Backward-Facing Step
(2016-06-21)Flow separation and reattachment happens in many fluid mechanical situations occurring in engineering applications as well as in nature. The flow over a backward-facing step represents a geometrically simple flow situation ... -
Hybrid Model for Micro-channel Heat Exchangers used in sCO2 Brayton Power Blocks
Studies have shown that Micro-channel Heat Exchangers (MCHEs) commonly referred to as Printed Circuit Heat Exchangers (PCHEs) are suitable candidates for recuperators and gas coolers used in sCO2 power blocks. CFD and 1-d ... -
Hydrodynamics Of An Oscillating Foil With A Long Flexible Trailing Edge
(2010-09-24)In nature, many swimming and flying creatures use the principle of oscillatory lift-based propulsion. Often the flapping element is flexible, totally or partially. The flow dynamics because of a flexible flap is thus of ... -
In Situ Transmission Elecron Microscope Triboprobe For Tribological Studies Of Materials At Nanoscale
(2013-09-10)In most of the tribological experiments studying friction and wear behaviour, the contact interface is hidden. The present work attempts to overcome this hidden-interface problem by carrying out real-time tribological ... -
In-Situ Polymer Derived Nano Particle Metal Matrix Composites Developed by Friction Stir Processing
(2018-08-10)Ceramic metal matrix composites (CMMCs) are materials generally created by mixing of hard ceramic particles in a metal matrix. They were expected to combine the ductility and toughness of the metal with the high strength ... -
Influence of Contact Stresses on Shape Recovery in Sputter Deposited NiTiCu Thin Films
(2017-10-05)NiTiCu is a shape memory alloy that regains its original shape after large amount of shape changing deformation when heated above a critical temperature called reverse martensitic trans-formation temperature( Af). When ... -
Influence of Hydrodynamic Slip on the Wake Dynamics and Convective Transport in Flow Past a Circular Cylinder
(2018-06-14)Hydrodynamic slip is known to suppress vorticity production at the solid-fluid boundary in bluff body flows. This suppression combined with the enhanced vorticity convection results in a substantial reduction in the unsteady ... -
Influence of Surface Topography and Roughness on Lubrication, Friction and Scuffing in High Hardness Steels
In tribology engineering, friction control is a significant challenge. The interacting surfaces of mechanical components are typically designed for best efficiency during tribological operations and are primarily achieved ...
