Asymptotic Analysis Of The Dispersion Characteristics Of Structural Acoustic Waveguides
(2010-04-12)In this work, we study the coupled dispersion characteristics of three distinct structural-acoustic waveguides, namely: -(1) a two-dimensional waveguide, (2) a fluid-filled circular cylindrical shell and (3)a fluid-filledelliptic ... -
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. ... -
Construction of 3D CAD Models From 2D Orthographic Views
(2011-01-19)This thesis addresses the problem of constructing 3D CAD models from 2D engineering drawings of the object. Procedures for each step in the popular bottom-up approach are described. In each of the steps in this approach, ... -
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 ... -
Cylindrical Fretting And Delamination : Axisymmetric Static And Dynamic Analysis
(2011-01-17)Axisymmetric analysis of cylindrical contacts is considered in the context of axisymmetric assemblies such as shrink-fits. Fretting fatigue induces sub-critical cracks along the contact interface of press fits especially ... -
Effect Of Mould Filling On Evolution Of Mushy Zone And Macrosegregation During Solidification
(2010-01-01)The primary focus of the present work is to model the entire casting process from filling stage to complete solidification. The model takes into consideration any phase change taking place during the filling process. An ... -
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 ... -
Finite Element And Experimental Studies On Fracture Behavior Of Bulk Metallic Glasses
(2011-01-19)The objective of this thesis is to study the fracture behavior of bulk metallic glasses. For this purpose, detailed finite element investigation of the mode I and mixed mode (I and II) stationary crack tip fields under ... -
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 ... -
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 ... -
Single Cavity Trapped Vortex Combustor Dynamics : Experiments & Simulations
(2011-04-06)Trapped Vortex Combustor (TVC) is a relatively new concept for potential use in gas turbine engines addressing ever increasing demands of high efficiency, low emissions, low pressure drop, and improved pattern factor. This ... -
Studies On Friction Stir Welding Of Precipitation Hardenable Aluminium Alloys
(2010-06-10)Friction Stir Welding (FSW) is an emerging solid state welding process. It has been a proven method for welding high strength aluminium alloys which were previously not recommended for conventional fusion welding. Since ... -
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 ... -
Study Of The Effect Of Elasticity Of The Added Mass In Mass Sensing Using Resonant Peak Shift Technique
(2013-05-21)Micromachined biosensors are used in chemical and biological applications. A biosensor which uses mass based transduction is called a mass sensor. Mass sensors are used to detect extremely small mass of biomolecules such ...
