A Testing of Fly Ash through the Mix up of Nano Silica for Difference of Strength in Concrete

Concrete is the most prevalent development material on the planet. It is made by blending fine and coarse aggregates, water, cement, and added substances in a specifically endorsed extent. Concrete has discovered use in a large variety of development shape parkway, channel, linings, scaffold, and dams to the most lovely and aesthetic of structures. The growth of reinforcement to supply required elasticity propels in bare outline, and pre pushing and post tensioning have turned into the premier auxiliary material. The most ultimate properties of concrete and workability of concrete rely upon aggregate. One would not consider utilizing wood for a dam, steel for asphalt, or black top for a building outline however, concrete is utilized for each of these and some different uses than other development materials. Indeed, even where another material is the main segment of a structure, concrete is normally utilized for specific work. It is utilized to help, to encase, to surface, and to fill. More individuals need to find out about concrete than about other specific materials.

Experimental Investigation of Stress Concentration in Cross Section of Crane Hook

Crane Hooks are highly liable components and are always subjected to failure due to the amount of stresses concentration which can eventually lead to its failure. To study the stress pattern of crane hook in its loaded condition, a solid model of crane hook is prepared with the help of solid works or Pro E software. Real time pattern of stress concentration in 3D model of crane hook is obtained. By predicting the stress concentration area, the shape of the crane is modified to increase its working life and reduce the failure rates. Hooks are employed in heavy industries to carry tonnes of loads safely. These hooks have a big role to play as far as the safety of the crane loaded is concerned. With more and more industrialization the rate at which these hooks are forged are increasing. This work has been carried out on one of the major crane hook carrying a larger load comparatively. The cad model of the crane hook is initially prepared with the help of existing drawings. It is then followed by implementation of modified cross section of hook in the static structural analysis workbench of ANSYS. The selection was based on the satisfaction of several factors in the form of load carrying capacity, stress induced and deflection Stress analysis plays a significant role in the design of parts and structures that must carry load. In this study, Crane hook which is one of lifting equipment, frequently used in material handling is investigated. Analytical Straight beam, curved beam and Winkler Bach approximation, FEM methods were used by various researchers to study stress pattern of crane hook in its loaded condition. The fatigue of the crane which leads to failure of propagation of cracks by stress concentration.

Progressive Collapse Analysis of Multi Storey Steel Structure with Bracing Systems using E Tabs

Progressive collapse refers to the phenomenon in which the local damage of a primary structural element leads to total or partial structural system failure, without any proportionality between the initial and final damage. Even if the probability of structural collapse is low, if it occurs, it can cause significant losses. In the past few decades, many incidents of the total or partial collapse of structures due to fire, explosions or impacts have occurred. In the present study, Multi storey structure is considered. The modelling and analysis are carried out using E tabs software. The different bracing systems are used to analysis the structural behavior. The Structure is later verified for progressive collapse analysis at 3 different locations such as corner, Centre and middle of the structure. The progressive analysis is carried out and results are extracted and discussed. The displacement control can be easily achieved by providing bracings. The displacement of bare frame models can be reduced by 55 , 55 and 63 by adopting bracings such as Diagonal bracing, V Bracing and X Bracing systems. The progressive collapse analysis shows the failure of upper level beams. It is estimated that, the maximum increase in percentage of DCR value for beams are around 38 , 52 and 59 for location A, B and C respectively. And hence the beams are super designed for these additional capacities to avoid progressive collapse. From the overall results, it is concluded that, the bracings are very much necessary for the reductions of displacement and drift effect in a building. However, its Importance is not of much use in case of progressive collapse state. The X Bracings are preferred for bracing system.

Finite Element Analysis of Ball Bearing for Different Materials

Bearing is an important part of a moving machine which is used for relative motion between the contact surfaces. Wear and tear of bearing is a common problem due to friction between the moving parts. A lot of researchers have done work for improving the life of the bearing. In the present work, traditionally used ball bearing has been modeled and analysed using FEM. Parameters such as Equivalent Von Misses Stress, Maximum Principal Stress, Equivalent Elastic Strain, Maximum Shear Stress and Total Deformation have been found out. Analysis has also been carried for finding out the effect of material of bearing steel, Structural Steel, Si3N4 and SiC on its performance along with elastic strain, stiffness and total deformation for various materials. It can be concluded that the Deformation and Elastic Strain induced in the SiC is less than the steel, structural steel and Si3N4 for the present investigation and the Stiffness of SiC is maximum as compared to steel, structural steel and Si3N4 hence SiC is the best material for ball bearing.

Thermal Performance of Diffusion Bonded Compact Heat Exchangers using Al2O3 Water Nanofluid

The value of compact heat exchangers CHEs has been recognised in aerospace, automotive, gas turbine power station, and other industries for the last 50 years or more. This is attributed to many reasons, for example manufacturing restrictions, often high efficiency requirements, low cost, and the use of air or gas as one of the fluids in the exchanger. Together with new and improved forms of CHEs, these advances are an excellent opportunity to bring compact heat exchangers into the process industry, particularly where saving energy is an essential target. High energy prices are also encouraging companies to use energy saving strategies at their plants as much as possible. During decades, attempts to increase heat transfer, decrease heat transfer times and eventually improve energy efficiency have been made. Recent advancements in nanotechnology have facilitated the creation of a new type of liquids called nanofluids. Most theoretical and computational experiments have shown that nanofluids demonstrate an improved coefficient of heat transfer relative to their base fluid. This CFD research explores the impact on the performance of straight square compact heat exchangers from Al2O3 water nanofluid flow. The Al2O3 water nanofluids with three weight fractions of nanoparticles i.e. 0.4, 0.8, and 1.2 percent were used. The effect of nanofluid were measured and observed to influence the heat transfer and flow of fluids in a straight square compact heat exchanger. The following conclusions can be drawn based on the provided results, the thermal conductance are approximately 29 higher and the heat transfer are approximately 35 higher in comparison with the conventional fluid i.e. water.
