  • The Physics Of Continuum Mechanics

    763 Words  | 4 Pages

    In continuum mechanics, a Newtonian Fluids is a fluid that the viscous stress arising from its flow, at every point, are linearly proportional to the local strain rate. The reason we research Newtonian Fluids is that Newtonian fluids are the simplest mathematical models of fluids that account for viscosity. In natural world, there are many common liquids and gases that can be assumed to be Newtonian Fluids. For example, water, alcohol, thin oil, air, and most of pure liquids. Newtonian fluids get

  • The Layer Of Thin Walled Structures

    970 Words  | 4 Pages

    Thin walled structures are an important part of engineering construction with territories of use becoming diverse continuously ranging from girder bridges, oil vessels to industrial warehouses , framed structures. Thin walled sections have various stresses and failure modes which can be difficult to predict. Thus structural engineers need help of computers for analysis of these structures. This has been done by using software called THIN-WALL which estimates the cross-sectional

    rotation of tensile axes can also be explained by the dominance of {112} slip systems at yield [48]. A ratio between the shear stress of the two most-stressed intersecting {112} slip systems below 1.1 correlates well with hardening at yield, suggesting that the combined twinning/anti-twinning and non-glide shear stress effects may only alter the critical resolved shear stress by a small amount [48]. Thus, many of these details may not be necessary for inclusion into practical models for the deformation

  • Spot Weld Analysis Of An Automobile Rim

    1209 Words  | 5 Pages

    Number of Spot welds on Automobile Wheel Rim using Finite Element Analysis is studied. Spot welded rim must pass certain tests like Weld Strength Test (WST), Dynamic Cornering Fatigue Test (DCFT) and Radial Fatigue Test (RFT). In Weld Strength test a shear force is applied on the spot weld using Universal Testing Machine. In dynamic cornering fatigue Test a moment is applied on the rim as specified by the company standards. In Radial Fatigue Test Influence of Tire pressure and vehicle load are studied

  • Formulation Of Rational Procedure And Comparison With Conventional Approach For Design Of Footings

    This is based on the procedure described by A. Luevanos Rojas et al (2013) and pursued for confirmation and comparison purposes. The pertinent equations with respect to flexure and shear are derived based on the general equation soil pressure at any point (x, y) below the footing as q(x,y)= P/A±M_(x )/I_X y ± M_(y )/I_y x 4.1 Notations and Equation for Soil Pressure below Rectangular Footing The notations used in Figure 3.2 refer

    which syneresis occurs, increases as the concentration of gelling agent decreases. The occurrence of syneresis indicates that the original gel was thermodynamically unstable. The mechanism of contraction has been related to the relaxation of elastic stress developed during the setting of the gels. As these stresses are relieved, the interstitial space available for the solvent is reduced, forcing the liquid out. C) Ageing Colloidal systems usually exhibit slow spontaneous aggregation. This process is

    induced forces. Stress is the lead to accurately describe and predict the elastic deformation of a body. Simple stress can be classified as normal stress, shear stress, and bearing stress. Normal stress develops when a force is applied perpendicular to the cross-sectional area of the material. If the force is going to pull the material, the stress is said to be tensile stress and compressive stress develops when the material is being compressed by two opposing forces. Shear stress is developed if

  • Intake Manifold Of Throttle Body Injection

    3932 Words  | 16 Pages

    Intake manifold of throttle-body injection/carburetion engines are designed to provide optimum flow of air-fuel mixture and to reduce the chances of the vaporized fuel re-condensation. Intake manifold runners on these engines have a few bends as possible. And it is one of the primary components regarding the performance of an internal combustion engine. An intake manifold is usually made up of a plenum, throttle body connected to the plenum and runners depending on the number of cylinders, which

  • The Boundary Layer Of An Object

    1594 Words  | 7 Pages

    1. The boundary layer is investigated for the situation that fluid is passing through an object, where around the object the layer of boundary is formed. Imagine the circumstance that the aircraft is flying in the sky, the wing is cutting through the air. The boundary layer around the wing could be observed, which is a thin and a highly sheared region. It is the layer that looks random and chaotic but also has structure on it. The Boundary layer is a complex structure, which is classified from Laminar
