Effect of Consideration in Euler Beam Theory
Abstract: The purpose of this paper is to improve the results of Euler beam theory. Euler beam theory can be used to determine the deflection of beam. But in some cases cross-section of beam is not flat-ended, and Euler beam theory only consider the vertical loading, so the effect of curvature is occurred due to normal loading. The method to determine the curvature effect has been developed in this paper, and …

Assumptions, Limitations and Applications of Bernoulli’s Equation
Abstract: The Euler-Bernoulli beam theory, also called “beam theory”, is a condensed version of the linearisotropic theory of elasticity and can be used to predict the load-carrying and deflection properties ofbeams. It was initially stated around the year 1750, but it was not widely used until the Eiffel Towerand the Ferris Wheel were built in the late 19th century. It immediately became an engineering pillarand a catalyst for the Second Industrial …

Structural Mechanics: Its Boundary Conditions and Applications
Abstract: Structural mechanics is the study of the calculation of deformations, deflections, internal forces, orstresses (stress equivalents) within structures, either for design or for performance assessment ofalready-existing structures. An area of structural analysis is this. Structural loads, the geometricrepresentation and support circumstances of the structure, as well as the material properties, are allinput variables for structural mechanics analyses. Support responses, strains, and displacementscould all be included in the output numbers. The …

Flexural Analysis of Thick Beam Subjected to Sine Load Using Refined Shear Deformation Theory
Abstract: A Hyperbolic Shear Deformation Theory (HPSDT) taking into account transverse shear deformation effects is used for the static flexure analysis of thick isotropic beams. The displacement field of the theory contains two variables. The hyperbolic sine and cosine function is used in the displacement field in terms of thickness coordinate to represent shear deformation. The transverse shear stress can be obtained directly from the use of constitutive relations, satisfying the …

Flexure of Thick Fixed Beams Subjected to Varying Load using Shear Deformation Theory
Abstract: A refined shear deformation theory for flexural analysis of thick beams, considering transverse shear deformation effects, is developed. The number of variables as in the first order shear deformation theory is kept in present theory. The important feature of present theory is that the transverse shear stresses can directly be obtained using constitutive relations. The theory does not demand shear correction factors. The principle of virtual work is used to …

Thermo-elastic flexural analysis of cross-ply laminated beams
Abstract: The present paper is concerned with the thermal analysis of symmetric and antisymmetric cross ply laminated beams subjected to temperature distribution across the thickness of laminated beam. A higher order shear deformation theory is used. The displacement field in terms of thickness coordinate is expanded up to cubic term to have a quadratic variation of the transverse shear strains and transverse shear stresses. This avoids the need of shear correction …
