The elastic foundation beam theory has been widely used in civil engineering, including railway, tunnel, and building foundations. With the development of fabricated structures, more beams need to be prestressed. In order explore frame with anchor-cable slope reinforcement project, this article, prestress is applied both ends beam. Then, according calculation method internal force deformation u...

In this paper, the bending behavior of rectangular plates with stepped thickness resting on an elastic half-space foundation is investigated through analytic method. Combined theory thin and moderately thick plate, plate divided into upper lower plates, Fourier series used to obtain analytical solution deflection interaction force between foundation. The influence modulus theory, dimension also...

Abstract In this article, the nonlinear dynamic responses of sandwich functionally graded (FG) porous cylindrical shell embedded in elastic media are investigated. The studied here consists three layers, which outer and inner skins made solid metal, while core is FG metal foam. Partial differential equations derived by utilizing improved Donnell’s theory Hamilton’s principle. Afterwards, Galerk...

This article serves as a continuation of our previously published work and focuses on loose material transport via sandwich belt conveyors. Experimental, analytical, stochastic, numerical approaches are used to obtain utilize the moduli bilateral Winkler elastic foundation that represent material, which is wheat (Triticum aestivum) free bran in this case. The solutions were obtained for uniform...

The bending and free vibration of porous functionally graded (PFG) beams resting on elastic foundations are analyzed. material features the PFG beam assumed to vary continuously through thickness according volume fraction components. foundation medium is also considered be linear, homogeneous, isotropic, modeled using Winkler-Pasternak law. hyperbolic shear deformation theory applied for kinema...

Numerous techniques have been presented by different researchers to analyze piled raft. In order to analyze pile foundation, soil can be modeled as spring, continuous medium, or porous media. Pile can also be modeled as spring or continuous medium. This study includes three main stages: a short description of different types of analysis methods of pile foundation, writing a computer program bas...

Transverse vibration of two axially moving beams connected by a Winkler elastic foundation is analyzed analytically. The system is a model of paper and paper-cloth (wire-screen) used in paper making. The two beams are tensioned, translating axially with a common constant velocity, simply supported at their ends, and of different materials and geometry. Due to the effect of translation, the dyna...
