Effect of Humidity and Temperature on Wear of TiN and TiAIN Coatings
(2018-05-30)When loss of material due to sliding of two solids is promoted/prevented, in the presence of chemically reacting liquid or gas, tribochemical wear is said to occur. Tribochemical wear, in which corrosive media promotes ... -
Effect of Interface Roughness on Mechanical Strength of Adhesively Bonded CFRP Joints- Experimental and Numerical Studies
Composite materials are well known for their superior properties such as specific strength, specific modulus, tailor-ability in different directions, fatigue resistance, durability, low weight, and low thermal expansion. ... -
The Effect Of Interference Of Strip Foundations And Anchors On Their Ultimate Bearing Capacity And Elastic Settlement
(2011-01-10)Due to close proximity of different civil engineering structures, the ultimate bearing capacity and failure pattern of adjoining footings/anchors are often influenced by their mutual interference. The present thesis is an ... -
Effect of Laser Shock Peening on Residual Stress and Mechanical behaviour of Aluminium alloy AA2219 Friction Stir Weld
The Aluminium alloy AA2219 is a precipitation-hardenable wrought alloy with copper as the major alloying element. Large-volume propellant tanks of space launch vehicles are manufactured by joining AA2219 alloy through ... -
Effect of Length Scale on High Temperature Mechanical Behavior of Sn-Cu Joints: A Mechanics and Material Science Based Treatment
With the ongoing miniaturization of microelectronic devices, the size of compliant solder in microscale solder joints has significantly reduced, proportion of brittle phases has increased, and the microscale joints have ... -
Effect of Li Addition on the Plasticity of AZ31 Mg-Alloy
(2017-11-14)Mg-alloys, despite being the lightest structural metallic materials, find limited applications due to their poor workability, which is due to the hcp structure that does not provide sufficient number of independent slip ... -
Effect of Microstructural Evolution on the Electrochemical Degradation Behaviour of Electrodeposited Tin-Based Coatings
The electrodeposited/electroplated Sn has been used as a protective coating to enhance corrosion resistance, anode material for rechargeable Li-ion battery as an alternative to graphite, decorative finishes, and electronic ... -
Effect of microstructure and texture on the dwell fatigue behaviour of titanium alloys
Ever since the failure of the fan blades of the Rolls Royce gas turbine engine that powered the Lockheed Martin tristar aircraft in 1972, ambient temperature dwell fatigue (DF) in titanium alloys has received considerable ... -
The Effect of Mismatch of Total Knee Replacement Components with Knee Joint : A Finite Element Analysis
(2018-01-10)It has been noticed that the need for total knee replacement surgery is increasing for Asian region. A total knee replacement is a permanent surgical solution for a patient having debilitating pain in knee joint suffering ... -
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 ... -
Effect of off-stoichiometry, grain size and chemical substitution on microstructure, global structure, electromechanical and energy storage properties of lead free Na0.5Bi0.5TiO3 (NBT) based piezoceramics
Ferroelectric and piezoelectric materials, especially the polycrystalline ceramics, are promising candidates for application in pressure sensors, actuators, transducers, ultrasonic motors, energy storage capacitors, ... -
Effect of Particle Shape on the Mechanical Behaviour of Granular Media : Discrete Element Simulations
(2018-03-08)Granular materials are characterized by its discrete nature which makes their behaviour very complex to understand when subjected to various loading situations. Comparing other materials, the understanding of granular ... -
Effect of particles on nonequilibrium relaxation phenomena in high temperature gas-nozzle flows
This thesis presents an exhaustive study of the effects of solid particles on the relaxation phenomena of various nonequilibrium processes, such as vibrational, dissociation and ionization, of the gas phase at high temperature ... -
Effect of pre-rotation on cavitation in centrifugal and mixed flow pumps.
It has been theoretically shown that introduction of prerotation at the impeller inlet at design point improves the cavitation performance. A qualitative assessment of this from existing data on centrifugal pump impellers ... -
