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 ... -

Intent- driven Correspondence and Registration of Shapes
(2018-05-29)Registration means to bring two or more shapes into a suitable relative configuration (position and orientation). In its major applications like 3D scan alignment, the aim is to coalesce data and regions originating from ... -
Interaction of Bubbles with Vortical Structures
(2017-09-23)Bubbly turbulent flows occur in a variety of industrial, naval and geophysical problems. In these flows, the bubbles in the flow interact with turbulence and/or vortical structures present in the continuous phase, resulting ... -
Investigation On Flexural Vibrations Of Bolted Laminates
(2013-07-02)Bolted cores made of coated silicon steel sheets constitute a vital part of heavy electrical equipment for transformers, motors and turbogenerators. Bolted laminates are eminently suitable for facilitating smooth magnetic ... -
Investigations On High Rayleigh Number Turbulent Free Convection
(Indian Institute of Science, 2005-08-31)High Rayleigh number(Ra) turbulent free convection has many unresolved issues related to the phenomenology behind the flux scaling, the presence of a mean wind and its effects, exponential probability distribution ... -
