(2009-06-30)Contact mechanical study of layered structures is useful to various fields of engineering, such as - mechanical engineering, civil engineering, materials engineering and biomechanics. Thin hard film coating on a compliant ... -
Inverse Sensitivity Methods In Linear Structural Damage Detection Using Vibration Data
(2009-06-29)The thesis addresses the problem of structural damage detection using inverse sensitivity based methods. The focus here is on characterization with regard to identification, location, and, quantification of structural ... -
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 ... -
Weighted Least Squares Kinetic Upwind Method Using Eigendirections (WLSKUM-ED)
(2009-06-24)Least Squares Kinetic Upwind Method (LSKUM), a grid free method based on kinetic schemes has been gaining popularity over the conventional CFD methods for computation of inviscid and viscous compressible flows past complex ... -
Evolution Of Multivariant Microstuctures With Anisotropic Misfit
(2009-06-17)Many technologically important alloys such as Ni base superalloys and Ti-Al base alloys benefit from the precipitation of an ordered β phase from a disordered α matrix. When the crystallographic symmetry of the β phase is ... -
Superplastic Deformation Behaviour Of AZ31 Magnesium Alloy
(2009-05-29)Superplastic deformation behaviour of AZ31 magnesium alloy having initial grain sizes 8, 11 and 17μm alloy was investigated at 673 K with initial strain rates ranging from 1x10-2 to 1x10-4 s-1. Mechanical data on fine ... -
Understanding Context In Designing
(2009-05-25)Everything around us that is not a simple untouched piece of nature has been designed by someone. Human society has found a great refuge in these designed objects or the artefacts, and thus has adapted vociferously to their ... -
Surface Energy Budget Over A Land Surface In The Tropics
(2009-05-21)Atmospheric convection is sensitive to the nature of the surface and its temperature. Both dry (without cloud) and moist (with cloud) convections depend on the surface temperature. Surface temperature is of critical ... -
Wood Fiber Filled Polyolefin Composites
(2009-05-19)The objective of the study is to improve the interfacial adhesion between the wood fibers and thermoplastic matrix. Efforts were also directed towards improving manufacturing processes so as to realize the full potential ... -
Study Of Fracture Properties Of NiAl Bond Coats On Nickel Superalloy By Three Point Bending Of Microbeams
(2009-05-13)The continuing quest for higher performance levels of modern gas turbine engines has been accompanied by the demand for higher engine operating temperatures. The use of Thermal Barrier Coatings (TBCs) enabled gas turbines ... -
Experimental Investigations Of Surface Interactions Of Shock Heated Gases On High Temperature Materials Using High Enthalpy Shock Tubes
(2009-05-12)The re-entry space vehicles encounter high temperatures when they enter the earth atmosphere and the high temperature air in the shock layer around the body undergoes partial dissociation. Also, the gas molecules injected ... -
