Abstract: This paper deals with Investigation for M-25 grade of concrete having mix proportion 1:1.50:3.17 with water cement ratio 0.465 to study the compressive strength, and Flexural strength of steel fiber reinforced concrete (SFRC) containing fibers of an interval of 0.5% from 0.0% to 1.5% volume fraction of hook end Steel fibers of 71 aspect ratio were used. The percentage of Fly Ash by weight is to be increased by 10% from 00% to 30%. After curing these specimen were tested as per relevant codes of practice Bureau of Indian Standard. A result data obtained has been analyzed and compared with a control specimen. A relationship between Compressive strength vs. days, and flexural strength vs. days represented graphically. Result data clearly shows percentage increase in7, 28 & 45 days Compressive strength for M-25 Grade of Concrete.

Abstract:The problems of flood wave propagation in bodies of waters caused by intense rains or floods represent a great challenge in mathematical modeling processes. With the progress of digital computers, the mathematical models become the great option in the analysis of this class problem. In this research, a finite element model developed for the prediction of flood routing in rivers. The developed model has been validated through comparing against other numerical model results and compared with observed data of a river reach. The developed model is capable of simulating the food hydrograph at any distance; the attenuation has been predicted accurately through the model. The results shows that the peak flow attenuation is non-linear trend in shape, which describes that at the initial stage, the attenuation of peak flow is greater as compared to the attenuation at the succeeding section/location at the downstream. However, this attenuation is going to be linear as the peak flow is moving towards the downstream end. The values for successive peak flow attenuation have also been computed which clearly demonstratethat this peak flow attenuation (PFA)has been diminished and remain negligible at some location on the downstream. The developed model is also capable of computing lag time which is necessary for the flood routing.

Abstract: In granite machining operation mainly the coolants used are viscous based coolants either kerosene, soluble mineral lard oil and water based coolants. By using water based coolants or solvents get maximum economy or less production cost than other coolants used in granite machining operation. While machining due to contact surfaces between granite block and cutting tool automatically there will be produce high heat due to high temperature cause, therefore the tool life may reduce surely. Hence there will be a minimum tool life, irregular finish of the cutting pieces and won't get dimensional accuracy. Material, due to increase in maximum heat. So everybody can use viscous lubricants in machining process that will give a cooling effect among the work piece, cutting tool and chip. Due to this result in machining get continuous chip without built up edge and also get maximum tool life because of low temperature produced at the cutting zone. Due to this low temperature also get accurate dimensions of the product. They are used to provide lubrication and cooling effects between cutting tool and raw block and chip during granite machining operation. Hence the influence of generated heat on cutting tool would be prevented as a result cutting fluids are used in granite machining for variety of reasons such as improving tool life, reducing work piece thermal deformation, improving surface finish and flushing away chips from the cutting zone. Choosing of viscous coolants depends on the type of raw blocks, cutting tool material and type of machining process.

Abstract: Modern production is based on the increased analysis of forming processes in digital environment before the actual production set-up to avoid the costly and complex experiments. The main aim of presented work is to approach the single stage deep drawing process of thin walled, mild steel, conical back plate of radial impeller of blowers by means of a finite element analysis. In the presented study, simulation of the drawing process for determining strain distribution pattern in the drawn component for a particular displacement is explained. The study was conducted by using ANSYS12.0, in which, two models have been tested. Both models constructed solely out of axisymmetric, quad 4 node, PLANE 42 elements. These axisymmetric models have been used to simulate the drawing process of drawing quality mild steel IS2062 grade. The experimental analysis is carried out on two different flat plates having thickness 3 mm and 5 mm from which the conical back plate is manufactured. This study will be useful to to the tool designer and the manufacturers doing work in this field.
