Interference Effects On The Collapse Loads For Footings And Anchors Using An Upper Bound Finite Element Limit Analysis
(2011-02-17)The present thesis is an attempt to investigate the interference effects on the magnitudes of the ultimate failure loads for a group of closely spaced strip footings and strip plate anchors. On account of an increase in ... -
Towards An Advanced 14-Node Brick Element For Sheet Metal Forming
(2011-02-15)Sheet metal forming is used in a wide range of industrial processes ranging from tube manufacturing to automobile and aviation industry. It includes processes like stamping, bending, stretching, drawing and wheeling. In ... -
A Unified, Configurable, Non-Iterative Guidance System For Launch Vehicles
(2011-02-10)A satellite launch vehicle not subjected to any perturbations, external or internal, could be guided along a trajectory by following a stored, pre-computed steering program. In practice, perturbations do occur, and in order ... -
Hydrologic Impacts Of Clmate Change : Quantification Of Uncertainties
(2011-02-10)General Circulation Models (GCMs), which are mathematical models based on principles of fluid dynamics, thermodynamics and radiative transfer, are the most reliable tools available for projecting climate change. However, ... -
Investigation Of Aerosol Characteristics Over Inland, Coastal And Island Locations In India
(2011-02-10)This thesis is based on measurements of aerosol optical and microphysical properties made at inland, coastal and island locations in India. Aerosol vertical distribution measurements have also been made both using surface ... -
Experimental Investigation Of Rheocasting Using Linear Electromagnetic Stirring
(2011-02-09)In several applications of casting, dendritic microstructure is not desirable as it results in poor mechanical properties. Enhancing fluid flow in the mushy zone by stirring is one of the means to suppress this dendritic ... -
Study Of Gas-Liquid Flow Behaviour In Raceway Zone Under Pulverised Coal Injection
(2011-02-09)Gas, liquid and powder flow in the lower part of a blast furnace is complex phenomena. In order to understand the aerodynamics of the blast furnace properly, these phenomena must be included in their advanced form. Previous ... -
Grain Boundary Processes In High Temperature Densification And Deformation Of Nanocrystalline Zirconia
(2011-02-08)Grain boundary processes play a major role in controlling different rate processes in yttria stabilized tetragonal zirconia. The present study concentrated on rate processes in tetragonal zirconia, which were significantly ... -
Understanding Knowledge Needs And Processes In Design
(2011-01-31)In this knowledge economy, organizations are leveraging their competence through the knowledge they possess. Managing knowledge will potentially retain the competence held by the organization if knowledge generated across ... -
Analysis Of Dense Sheared Granular Flows
(2011-01-27)A granular material is a collection of discrete, solid particles of macroscopic size dispersed in an interstitial fluid, in which the fluid has an insignificant effect on the particle dynamics. Because they exhibit fascinating ... -
Non-Linear Finite Element Analysis Using Strain-Space Plasticity Coupled With Damage
(2011-01-27)The Thesis deals with Strain-Space Plasticity and its implementation in Nonlinear Finite Element frame-work coupled with damage. Conventional Stress-Space Plasticity, though very popular amongst commercial nonlinear FEM ... -
Investigations Of Polymer Grafted Lipid Bilayers Using Dissipative Particle Dynamics
(2011-01-25)Lipid molecules are amphiphilic in nature consisting of a hydrophilic head group and hydrophobic hydrocarbon tails. The lipid bilayer consists of two layers of lipid molecules arranged with their hydrophobic tails facing ... -
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, ... -
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 ... -
