A Unified Constitutive Model For Large Elasto-plastic Deformation
(2009-07-23)
Rapid development and stiff competition in material related industries such as the automotive, demand very high precision in end products in very quick time. The transformation of raw material into an intricate-shaped final ...
Analytical, Numerical, And Experimental Studies Of Fluid Damping In MEMS Devices
(2009-09-11)
Fluid damping arising from squeeze film flow of air or some inert gas trapped between an oscillating micro mechanical structure, such as a beam or a plate, and a fixed substrate often dominates the other energy dissipation ...
A Finite Element Investigation Of Brittle Fracture During Spherical Nanoindentation Of Thin Hard Films
(Indian Institute of Science, 2006-12-14)
Hard ceramic films of micrometric thickness deposited on a soft metallic substrate have ushered in a new era in the fabrication of structural, tribological, microelectronic and optical components. The mechanical performance ...
Studies On Momentum, Heat And Mass Transfer In Binary Alloy Solidification Processes
(Indian Institute of Science, 2007-06-06)
The primary focus of the present work is the development of macro-models for numerical simulation of binary alloy solidification processes, consistent with microscopic phase-change considerations, with a particular emphasis ...
An Experimental Study Of Instabilities In Unsteady Separation Bubbles
(Indian Institute of Science, 2007-06-11)
The present thesis is an experimental study of some aspects of unsteady two dimensional boundary layers subject to adverse pressure gradient. An adverse pressure gradient usually leads to boundary layer separation or an ...
Development Of A Single Cylinder SI Engine For 100% Biogas Operation
(Indian Institute of Science, 2007-05-21)
This work concerns a systematic study of IC engine operation with 100% biogas as fuel (as opposed to the dual-fuel mode) with particular emphasis on operational issues and the quest for high efficiency strategies. As a ...
Transport Phenomena In Laser Surface Alloying: A Numerical Investigation
(Indian Institute of Science, 2006-08-24)
A comprehensive, transient three-dimensional model of a single-pass laser surface alloying process has been developed and used to examine the heat, momentum and species transport phenomena. A numerical study is performed ...
Modular Kinematic Analysis Of Planar Linkages
(2009-04-24)
This thesis has developed an efficient methodology for automatic kinematic analysis of planar linkages using the concept of modular kinematics. Unlike conventional general purpose kinematic analysis packages where each joint ...
Cooling Of Electronics With Phase Change Materials Under Constant Power And Cyclic Heat Loads
(2009-12-14)
The trend in the electronic and electrical equipment industry towards denser and more powerful product requires a higher level of performance from cooling devices. In this context, passive cooling techniques such as latent ...
Experimental And Finite Element Study Of Elastic-Plastic Indentation Of Rough Surfaces
(2009-06-24)
Most of the surfaces have roughness down to atomic scales. When two surfaces come into contact, the nature of the roughness determines the properties like friction and wear. Analysis of the rough surface contacts is always ...
