Abstract: Analysis of any fames (or) truss by conventional method is very difficult and time consuming process which may leads to error in calculation of results. In order to overcome this problem most of them will use ANSYS software to analyze the frames and truss cases. ANSYS is general purpose software used to simulate interactions of all disciplines of physics, structural, vibrations, fluid dynamics, heat transfer and electromagnetic uses for engineers. In this paper analysis of double Howe steel truss and cantilever truss are carried out and the results of nodal deflections, stresses in elements for both cases were determined.

Title	:	The Use Of Mixed Eulerian-Lagrangian Displacement In Analysis Of Prestressed Concrete Bridge Girder
Country	:	Indonesia
Authors	:	Binsar H. Hariandja
	:	10.9790/1684-1406021523

Abstract: The paper discusses the use of mixed Eulerian-Lagrangian in the analysis of post-tensioned prestressed concrete bridge girder. The hose of the tendon is in stick condition with the surrounding concrete while the tendon in slip condition with the hose. The slip between the tendon with the hose is modeled by means of Eulerian displacement. The girder concrete is modeled by using brick elements while the tendon is modeled by using bar elements. The quadratic shape of tendon is modeled by piece-wise linear bar elements arrangement. If finite element mesh is construed to follow quadratic shape of tendon, then irregular shape of elements may results. To avoid this, the nodes on bar elements are connected to girder mid nodes with rigid bars. Bottom ends of bars are connected............

Title	:	Emission reduction in automobile engine exhaust using bio catalytic converter: An Experimental Study
Country	:	India
Authors	:	Rahul Ganji || VN Yenugula
	:	10.9790/1684-1406022428

Abstract: Automobile vehicle engine exhaust after treatment design has become very important because exhaust emissions standards are ever increasing. Catalytic converter is a main apparatus for eliminating the pollutants in engine exhaust. There are challenging problems to the emission control designers especially demanding different standards in exhaust gas conditions. In order to adopt stringent emission regulations, engine requires more vigorous and durable catalysts as well as optimized exhaust system design. To achieve the emission levels well below the standard regulations a specially designed bio catalytic converter is incorporated with the existing three way catalytic converter. Algae are used in specially designed bio catalytic converter. Experimental investigations were carried out with specially designed bio catalytic converter and found reduced emission levels in comparison with three way catalytic converter.

Abstract: Functionally Graded Materials (FGMs) are the advanced materials in the field of composites, which can resist high temperatures and are proficient in reducing the thermal stresses. In recent decades, significant investigations are reported in the predicting the response of FGM plates subjected to thermal loads. This paper presents a comprehensive review of developments, various mathematical idealizations of materials, temperature profiles, modelling techniques and solutions methods that are adopted for the thermal analysis of FGM plates. An attempt has been made to classify the various analytical and numerical methods used for the vibration and buckling analyses of FGM plates under one dimensional or three-dimensional variation of temperature with constant /linear /nonlinear temperatures profiles........

Abstract: In this paper, a wind turbine gearbox model, which is realized through a Bond Graph Approach, is presented to analyze the dynamic behavior of a wind turbine transmission. In this regard, the wind turbines gearbox consists of three stages. The first one is a planetary gear and the two others are parallel gears. Taking account of meshing and torsional stiffness and dumping, the dynamic model of each stage is established. Consequently, the whole model is integrated following the Bond Graph modeling procedure. Subsequently, vibration analysis of the gearbox is carried out to demonstrate the application of the Bond Graph model in mode analysis. Finally, the dynamic characteristics of a wind turbine gearbox using the proposed model are analyzed and verified based on 20-sim program.

Abstract: The design of a wind turbine system (sizing, control), needs the use of performing simulation tools agreeing to specifications in terms of quality of produced electricity, stability and safety. The effects of the wind speed change, the variation of cinematic movement parameters, the structure aero elastic response and the definition of subsystems characteristics that makes the entire wind turbine system, including blades, tower, drive train, rotor and control system allow one to characterize the structural dynamic behavior of the wind turbine. This paper presents a novel methodology to study the dynamic behavior of wind turbine blades with horizontal axis using the Bond Graph Method........

Abstract: With generator load as the key factor, this paper focuses on both maintenance and running equipment parameters and their effect on the load. The parameters of interest in this studywere turbine inlet pressure, steam flow rate, steam chest pressure (Bowl pressure) and generator loading. For this study, Olkaria II power station data was used. From this data, it was observed that after a few years of operation, even with the steam chest pressure increasing from 2.5 bar g to 4.1 bar g and increase in steam consumption the turbine power generation decreased to 26.4Mw out of the rated capacity of 35.0Mw. This led to dismantling of the turbine in question for inspection which led to the discovery that significant Sulphur deposition, scaling and related compounds had occurred thus reducing.......

Abstract: High-performance composite materials exhibit both anisotropic strength and stiffness properties. These anisotropic properties can be used to produce highly-tailored aircraft structures that meet stringent performance requirements, but these properties also present unique challenges for analysis and design. Composite materials can provide a much better strength-to-weight ratio than metals. The lower weight results in lower fuel consumption and emissions and, because plastic structures need fewer riveted joints, enhanced aerodynamic efficiencies and lower manufacturing costs. This paper examines the design of metallic and composite aircraft wings in order to assess.......
