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 ...
Axially Homogeneous Turbulent Convection at High Rayleigh Numbers : Scaling Laws for Flux and Spectra
(2018-05-30)
Natural turbulent convection studies encompass a wide range of flows occurring in nature, for example, atmospheric and oceanic flows, con-vection in the Earth’s mantle, convection in the stars and also in many engineering ...
Studies on the Effect of Process Aspects on Material Mixing and Defect Formation in Friction Stir Welding
(2018-05-30)
Friction Stir Welding (FSW) is a rapidly growing solid state welding process and has been a proven method for welding high strength aluminium alloys which were formerly not recommended for joining by conventional fusion ...
Modeling of the Haltere-A Natural Micro-Scale Vibratory Gyroscope
(2018-06-05)
Vibratory gyroscopes have gained immense popularity in the microsystem technology
because of their suitability to planar fabrication techniques. With considerable effort in design and fabrication, MEMS (Micro-electro-mec ...
Numerical Modelling and Software Development for Analysing Squeeze Film Fffect in MEMS
(2018-06-05)
The goal of the current study was to develop a computational framework for modelling
the coupled fluid-structure interaction problem of squeeze films often encountered in
MEMS devices. Vibratory MEMS devices such as ...
Estimation of Stress Concentration and Stress Intensity Factors by a Semi-Analytical Method
(2018-05-29)
The presence of notches or cracks causes stresses to amplify in nearby regions. This phenomenon is studied by estimating the Stress Concentration Factor (SCF) for notches, and the Stress Intensity Factor (SIF) for cracks. ...
Generalized Circular and Elliptical Honeycomb Structures/Bundled Tubes : Effective Transverse Elastic Moduli
(2018-01-01)
Omnipresence of heterogeneity is conspicuous in all creations of nature. Heterogeneity manifests itself in many forms at different scales, both in time and space. Engineering domain being an exotic fusion of human creativity ...
Micro-Mechanisms Associated with Friction Stir Welding of Aluminum with Titanium
(2018-01-10)
Out of the known aerospace metal and alloys, Aluminium (Al) and Titanium (Ti) are important due to their unique combination of properties, such as strength, ductility and corrosion resistance etc. For these reasons, welding ...
Experimental Study of Flow Past a Circular Cylinder with a Flexible Splitter Plate
(2018-01-04)
A circular cylinder is a geometrically simple bluff body that occurs in various practical applications. As with any bluff body, it exhibits large drag forces and a strong fluctuating lift force, both related to the strong ...
Nano Porous Alumina Based Composite Coating for Tribological Applications
(2018-02-06)
Anodisation is a surface treatment process, commonly used to form a protective oxide coating on the surface of metals like aluminium. Anodised coatings, being grown out of the base metal have excellent interface strength ...
