Laminar Conjugate Natural Convection And Surface Radiation In Horizontal Annuli
(2010-07-29)
Numerical studies of two-dimensional laminar conjugate natural convection flow and heat transfer in horizontal annuli formed between inner heat generating solid cylinders and outer isothermal circular boundary are performed ...
Transfer Layer Formation And Friction In Extrusion Of Aluminum : An Experimental Study Using A High Temperature Vacuum Based Pin-On-Disc Machine
(2010-09-21)
Hot extrusion of aluminum is widely practiced in industries for economic production of structural components. The surface finish and tolerance of the extruded components, both from design and aesthetic requirement, are ...
A Study Of Four Problems In Nonlinear Vibrations via The Method Of Multiple Scales
(2010-12-03)
This thesis involves the study of four problems in the area of nonlinear vibrations, using the asymptotic method of multiple scales(MMS). Accordingly, it consists of four sequentially arranged parts.
In the first part ...
Constraint Effects On Stationary Crack Tip Fields In Ductile Single Crystals
(2011-03-15)
In order to understand and predict the fracture behaviour of polycrystalline materials from a fundamental perspective, it is important to first investigate plastic deformation at a crack tip in a ductile single crystal. ...
Role Of Mixed Convection In Cooling Of Electronics
(2011-03-15)
Cooling of electronic components is one of the most important issues concerned in the electronic industry for design of equipment. Maintaining the temperature of an electronic device within its safe operating temperature ...
Kinematic And Static Analysis Of Over-Constrained Mechanisms And Deployable Pantograph Masts
(2011-01-19)
Foldable and deployable space structures refer to a broad category of pre-fabricated structures that can be transformed from a compact folded configuration to a predetermined expanded configuration. Such deployable structures ...
Stability Of Double-Diffusive Finger Convection In A Non-Linear Time Varying Background State
(2010-09-06)
Convection set up in a fluid due to the presence of two components of differing diffusivities is known as double diffusive convection. Double diffusive convection is observed in nature, in oceans, in the formation of certain ...
Experiments On Natural Ventilation In A Room And Real Source-Sink Pairs
(2010-09-06)
The present work consists of two parts: experimental study of natural ventilation in a model room and the flow associated with a source-sink pair.
The first part describes the natural ventilation of a model room of size ...
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 ...
Experimental And Theoretical Studies In Fatigue Damage Modeling
(2010-12-07)
This thesis has two parts.
In the first part, we use the results of new fatigue experiments conducted with variable load levels as well as variable stress ratios to critically assess three (two old and one relatively ...
