for dynamic analyses of railway track structures, the algorithm of solution is very important. for estimating the important problems in the railway tracks such as the effects of rail joints, rail supports, rail modeling in the nearness of bridge and other problems, the models of the axially beam model on the elastic foundation can be utilized. for studying the effects of axially beam on the ela...

Ion implantation of titania nanotubes is a highly versatile approach for tailoring structural and electrical properties. While recently self-organized nanoscale compositional patterning has been reported, the atomistic foundations impact on electronic structure are not established at this point. To study these aspects, ab initio molecular dynamic simulations based atomic compositions in C impla...

Abstract This article re-examines the nonlinear vibration and bending responses of porous sandwich cylindrical panels reinforced by graphene platelets resting on elastic foundations in thermal environments. The platelet-reinforced composite (GPLRC) core is assumed to be multilayers, each layer may have different porosity coefficient values achieve a piece-wise functionally graded pattern. By in...

The Univalent Foundations of Mathematics (UF) provide not only an entirely non-Cantorian conception of the basic objects of mathematics (“homotopy types” instead of “sets”) but also a novel account of how foundations ought to relate to mathematical practice. In this paper, I intend to answer the question: In what way is UF a new foundation of mathematics? I will begin by connecting UF to a prag...

this paper presents a description of the equipment, testing procedure, and methodology to obtain ground mechanical parameters. the p-y curves for laterally loaded piles are developed. methods for the development of p-y curves from pressure meter and dilatometer (dmt) test are described. p-y curves are used in the analysis to represent lateral soil-pile interaction. the pressure meter offers an ...

In the present paper, a class of partial differential equations related to various plate and rod problems is studied by Lie transformation group methods. A system of equations determining the generators of the admitted point Lie groups (symmetries) is derived. A general statement of the associated groupclassification problem is given. A simple intrinsic relation is deduced allowing to recognize...

Abstract—Numerical study of the static response of homogeneous clay stratum considering a wide range of cohesion and subject to foundation loads is presented. The linear elastic–perfectly plastic constitutive relation with the von Mises yield criterion were utilised to develop a numerically cost effective finite element model for the soil while imposing a rigid body constrain to the foundation ...
