This paper compares two different accident sequence methodologies for external flood probabilistic safety analysis (EFPSA). It is shown that the two methodologies lead to identical expression for CDF with an example. Using accident sequences developed for internal events PSA is recommended for detailed external flood…
Carbidic Austempered Ductile Iron (CADI) is a recent addition to the Austempered Ductile Iron (ADI) family. The effect of chills on the microstructure and mechanical properties of CADI was investigated after Austempering. Three samples of chromium alloyed CADI, the first sample without chill, the second sample with bo…
Generally, vehicle safety is a vital issue in the field of automobile industry. Ensuring the safety of passengers is one of the prime challenges for vehicle design engineers. Automobile safety can be determined from the ability of vehicle structure and its internal support systems to protect the occupants from injurie…
The corrosion behavior of AZ61 alloyed with 0.5, 1.0, 1.5 and 2.0% Ca were studied by potentiostatic polarization technique in 3.5wt. % NaCl solution and the further effect of corrosion behavior have been studied after aging at different temperature in a controlled environment.The results show that the calcium additio…
The exothermic behavior of Tributyl Phosphate (TBP) with nitric acid at elevated temperatures is a serious cause of concern in nuclear industry as well as in various other industries where it is the principal extractant. In this study, the comparative study of thermal hazard of TBP and one of its major decomposition p…
The properties of fiber reinforced composites (FRP) like high strength to weight ratio, high stiffness to weight ratio, flexibility in design, ease of fabrication with economical savings as compared to metal alloys, make it an excellent choice for various range of products from building materials, sporting equipment,…
Since carbon nanotubes were discovered, till now no definitive formulation for computing the shear modulus of them was presented. To develop a theoretically rigorous and mathematically elegant expression for the shear modulus, thus, we initially propound a new small-strain theory in which merely small strain will aris…
Prototype fast breeder reactor’s (PFBR) secondary pumps have sealing between the rotating shaft and the stationary parts to prevent cover gas leakage into ambient air. This is achieved by means of triple mechanical seals with oil as buffer fluid. The oil for cooling the mechanical seals and bearing is supplied from an…
An attempt has been made in this research work to develop strong and tough bainitic steels in shorter transformation durations of less than three hours leading to ease of production for steel industries making these steels. High carbon medium alloy steel with high amounts of silicon, cobalt and aluminum was taken up f…
A three-dimensional microfluidic biosensor has been successfully designed using a low temperature co-fired ceramic (LTCC) technology. This microfluidic sensor consists of mixing, focusing and measuring region. The mixing region is a rectangular shaped channel, to enable the complete mixing of sample and buffered salin…
The main aim is to control thermal expansion in aluminium piston at high working condition. A plasma sprayed ceramic coating (TBC) is applied on the piston crown as a top coat and NiCrAl is applied as the middle layer as bond coat to improve the addition strength between the top coat and the metal subtract layer as Al…
PVC insulation has extensively been used for insulating low voltage electrical cables. They offer superior insulating properties but how ageing and exposure could affect their insulation properties is a matter of concern. Chemical exposure related failure modes are known but have received only limited study. The tradi…
The study of evaporation of water droplets over horizontal heated surfaces is an intense area of research because of its wide application in various fields of heat transfer. The characterization of the behavior of water droplets is important in studying the cooling effects produced over impinging surfaces. The present…
The material development is aimed at utilizing a suitable Metal Alloy in combination with a most appropriate plastic material considering the achievement of desirable basic features of Smart materials like Shape Memory Effect, Flexibility, recovery time etc. In the present work shape memory composites were developed u…
In recent year’s Natural Fibers reinforced composite (NFRC) are considered as a suitable alternative to engineering material due to their advantages like low cost, low density, high strength and stiffness to weight ratio, resistance to breakage during processing, low energy consumption, a lesser amount of pollutant em…
In the present work, an attempt has been made to explore the general microstructural characteristics and mechanical properties of titanium-titanium boride (Ti-TiB) composites (20 and 40 vol.% TiB reinforcement in Ti matrix) processed by Vacuum Sintering. The microstructures of the composites were investigated using el…
This paper presents comparison of magnetoelastic properties between the 〈110〉 oriented Tb x Dy 1-x Fe 1.95 polycrystalline alloys for x = 0.27, 0.3, 0.45 under coupled loading of magnetic field and compressive stress. The simultaneously measure are investigated for the magnetization and magnetostriction under applied…
In this work we have satisfied the objective to analyse the medium carbon steel rods which are welded frictionally on their tensile properties when the welding parameter is maximum and minimum in values of forging pressure with respect to time. This work also carries the macrostructure and microstructure analysis of t…
Diamond-like-carbon (DLC) coatings provide excellent surface properties on substrate. With novel advanced techniques like modeling and simulation, the performance of these coatings can be predicted under different loading condition. Aim of present study was to developed three dimensional models for calculating first p…
