Abstract: This paper describes the design and experimental analysis of composite leaf spring made of glass fibre reinforced polymer. The main aim is to compare the load-carrying capacity, stiffness and weight savings of composite leaf spring with that of steel leaf spring. The design constraints are stress and deflection. The dimensions of an existing conventional steel leaf spring of a light commercial vehicle were considered for the present work. A traditional composite multi-leaf spring was fabricated with the same dimensions using E- Glass/Epoxy unidirectional laminates. Static analysis of 2D model of conventional leaf spring has also been performed using ANSYS 10 and compared with experimental results. Finite element analysis with a full load on the 3-D model of composite multi- leaf spring was performed using ANSYS, and the analytical results were compared with experimental results.....

Abstract: Soil loss in our environment is a very serious issue and has caused great damage to business activities. It poses serious hazard to properties. Many models and theories have investigated soil loss in various perspectives, while Empirical Soil Loss Regression Model (ESLRM) had approached it using empirical methods. This study focuses on the effect of those experimental parameters used or employed in (ESLRM). The parameters includes rainfall intensity I, Slope of the catchment S, Duration of the rainfall D, Soil density,, size of catchment area A, Organic content, O and Clay content of the soil C. From the model equation, intensity, slope, duration, density and Area represent the erosive effect in soil loss operation with their power coefficient being positive, while organic content and clay content of the soil represent the erodibility component of soil loss operation with negative sign in their power coefficient. A total of thirty-two experiments were conducted, nine of which were used to develop the model.....

Abstract: Both the central and state Government are spending huge amount of money for abatement of pollutions to the river Ganga. Now G.O.I has introduced a "Namami Ganga Mission" where the sewage from every house, from the municipal drains and canals have been Intercepted and Diverted to the Sewage Treatment Plant via Lifting Stations, and discharging the same after treatment. Constructional activities in all those processes are huge and monetary involvements are also fabulous. So, in-situ treatment in the canals and drains may be a solution to tackle the pollution loads directed to rivers and hence in-situ treatment like Bio-remediation, Phyto-remediation, attached-growth etc. are now used in different locations. But in case of in-situ treatment by Depth Filtration is unique one as the process is cost effective, monetary involvement is very less. The Whole unit may be installed above the HFL of the canal so that it may not affect the normal flow of the canal. The effluent standard obtained from this treatment is quite satisfactory and BOD, COD and TSS removal efficiency in the Depth filter process is 98%, 96% and 99% approximately from highly polluted sewage.

Abstract: Currently concrete is most demanding material for the construction of various infrastructural activities. Concrete has become a basic need for every structure at the present time. The growingresidents of the world puts a major concern to develop a cost effective as well as an eco-friendly structure according to the need of human beings. To identify the suitability of ceramic waste and stone powder as fine aggregate, cylindricalsamples were casted at different composition of ceramic waste and stone powder.The compressive and split strengthwere tested and compared withreference concrete.Theexperimental resultsshows thatthe strength developed in concrete increased and cost analysis estimated that partial replacement of ceramic waste and stone powder as fine aggregate reduced the cost of concrete

Abstract: This study was initiated to find the Specific Fuel Consumption (SFC) of single cylinder diesel engine operating on palm seed biodiesel and compare them with SFC of engine when operated on pure diesel and blend of 40% diesel and 60% palm seed biodiesel. The aim of this study was to determine and compare the effects of variable parameters like Blend ratio, Compression ratio, Injection pressure and load on performance parameter, Specific fuel consumption. Since there are higher number of parameters and levels, the number of probable models is high. So, for selection of optimum parameters, huge analysis work is required which takes somuch time. To neglect this problem, Taguchi method is used. The set of combination for factors and levels are achieved with the help of orthogonal array

Abstract: To simulate corrosion deterioration on load carrying capacities, deflection and slip between concrete and steel for R.C. beams, a 3-D F.E. model was considered by using ANSYS software. Several F.E. models were created to simulate different levels of corrosion. In this model, both concrete and steel were modelled as solid elements and stirrups were represented as link elements. To consider corrosion effects which can be represented by reduction in steel cross section and decrease in bond between concrete and steel, contact element between two bodies was created. Also, analytical calculations were driven to calculate load carrying capacities, deflection and slippage distance. The results of both models were acceptable within average error about 10%.

Abstract: The current study aims to investigate the effect of adding Nano-silica (NS), Nano metakaolin (NMK), and Nano cement (NC) with various ratios into the expansive soil.The effect of adding nanomaterials on soil physical properties was measured. Then, Energy-dispersive X-ray (EDX) and Scanning Electron Microscopy (SEM) were performed to study the microstructure of the swelling soil.Finally, the effect of adding the previous three nanomaterials on the swelling indices of swelling soil was obtained. According to the results, NMK and NS improve soil swelling at a 2%addition ratio, while NC performs better at a ratio of 3%. SEM and EDX analysis showed that the small particle size for the.........

Abstract: The inclusion of randomly oriented fibres in concrete has been studied experimentally by various researchers. The influence of various types of fibres on the mechanical behavior of concrete is characterized by the residual flexural strength obtained from three-point bending tests on notched beams. However, the numerical behaviour of fibre reinforced concrete members has not been investigated to a great extent despite the significance of precise modelling of post-cracking behaviour of Fibre reinforced concrete and its relevance to the stress-distribution in concrete and reinforcing bars. This paper presents the results from the finite element analysis performed to study the behaviour of synthetic FRC prisms and compares........
