Abstract: This paper describes static and dynamic analysis of steel propeller shaft and composite propeller shaft made of glass fibre reinforced polymer. Primary objective is to compare the torque bearing capacity, stiffness and weight savings of composite propeller shaft with that of steel propeller shaft. The design constraints are angle of twist and natural frequency. Finite element analysis with full torsional load on 3-D model of composite propeller shaft was done using finite element technique and analytical results were compared with experimental results. Composite propeller shaft had greater angle of twist, higher stiffness and higher natural frequency than that of existing steel propeller shaft. A weight reduction is achieved by using composite propeller shaft.
Keywords: Composite propeller shaft, Glass fibre reinforced polymer, Angle of twist, Natural frequency, Static analysis, Dynamic analysis

Abstract: Now days the world is focusing into automation. Each and every work of human is reduced by a machine, but few areas like construction the usage of machines for bending rods for stirrups which are used to withstand loads in beams and columns are not done by machine because the cost of machine is high and need skilled labor to operate it. So this project is aimed to do bending operation for stirrups using mechanical application and named as automatic stirrup making machine.

Abstract: Sandwich beams offer designers a number of advantages, such as high stiffness to weight ratio, high bending, and buckling resistances, ….etc. which are useful in aerospace, and mechanical engineering designs as well as in renewable-energy applications e.g. wind mill blades. In the present study the effects of the different sandwich beam parameters, such as; face and core thicknesses, beam width and length on the dynamic performance of steel/wood sandwich beams have been investigated as compared with a steel solid beam with the same dimensions. The damped-and undamped natural frequencies of the beams have been determined both theoretically and experimentally.

Abstract: This paper discuss about evaluation of stresses of tubesheet joint and axial deformation of shell and tubes of heat exchanger for dewaxing application under transient thermal loading. Two models of tube and tubesheet, one using tubes as beams and other using tubes as springs has been used to calculate stresses at tube and tubesheet junction. Axial deformation of shell and induced stresses at tube-to-tubesheet junction obtained by both models are in close comparison with each other but the computational solution time required for model with sprigs is almost 38% less than for model with beams.

Abstract: Many infrastructure projects such as highways, railways, water reservoirs, reclamation etc. requires huge earth material. In such a way to enhance the engineering properties of the soil, it requires various soil stabilization techniques. Soil stabilization is used very widely for the construction of road pavement and foundation construction, to enhance engineering properties such as strength volume stability and durability.

Abstract: This study highlights the possibility of using GA (Genetic Algorithm) in everyday design. The global optimization of a frame using linear buckling of 3D model was introduced. The proposed optimal model is compared to the commonly used member checks with interaction formula based on Egyptian code of practice. The results of the proposed model clearly point the advantages of using GA, instead of the classical member checks. The proposed model was used in a parametric study, many influential factors were studied, and then the design recommendations are introduced. The study shows that no need for using lower flange bracing, since the optimal model presents the section dimensions to resist lateral buckling. Using non-compact section and the recommended span-to-depth ratio were introduced as a design guideline.

Abstract: Since the ancient times, many researches and advancements were carried to enhance the physical and mechanical properties of concrete. Fibre reinforced concrete is one among those advancements which offers a convenient, practical and economical method for overcoming micro cracks and similar type of deficiencies. Since concrete is weak in tension hence some measures must be adopted to overcome this deficiency. Human hair is generally strong in tension; hence it can be used as a fibre reinforcement material. Human hair Fibre is an alternative non-degradable matter available in abundance and at cheap cost. It also creates environmental problem for its decomposition.

Abstract: Concrete is a mixture of cement, fine aggregate, coarse aggregate and water. Concrete plays a vital role in the development of infrastructure Viz., buildings, industrial structures, bridges and highways etc. leading to utilization of large quantity of concrete. On the other side, cost of concrete is attributed to the cost of its ingredients which is scarce and expensive, this leading to usage of economically alternative materials in its production. This requirement is drawn the attention of investigators to explore new replacements of ingredients of concrete.

Abstract: The trend of research in the automotive industry is towards mass green transportation with high speed and efficiency. Ground Effect Vehicles (GEV) is one of the choices with good Lift-Drag Ratio at high speeds. The research paper deals with the investigation of flow field over the NACA 6321 flat bottom aerofoil under the effect of ground. Experimental investigation of pressure distribution over the aerofoil with and without ground effect is carried out for various angles of attack (AOA) and height-chord (h/c) ratio. The results from experiments are compared with numerical results.

Abstract: The aim of this experimental investigation is to increase awareness amongst the researchers and to draw their attention towards the present approach to deal with the cryogenic treatment for the nonferrous metals. Cryo means cold born crystal structure in metallurgical aspect. Cryogenic treated nonferrous metals will exhibit longer wear and more durability. During metal making process, when solidification takes place, some molecules get caught in a random pattern. The molecules do move about at subzero and deep cryogenic treatment slowly. In this experimental study the effect of cryogenic treatment on microstructure changes and the hardness properties varies for LM25 alloy and LM25-TiO2 metal matrix composite at -196°C.It is analyzed for different durations.
