In this paper, a Green’s function is developed for bending analysis of micro plates under an asymmetric load. In order to consider the length scale effect, the modified couple stress theory is used. This theory can accurately predict the behavior of micro structures. A thin micro plate is considered and therefore the classical plate theory is utilized. The size dependent governing equilibrium e...

Although segmental tunnel linings are often used for seismic areas, the influence of segment joints on the segmental lining behavior under seismic loading has not been thoroughly considered in the literature. This paper presents the results of a numerical study investigating the effects of the rotational, axial, and radial joint stiffness of the longitudinal joints on the structural force...

Insect antennae are important mechanosensory and chemosensory organs. Insect appendages, such as antennae, are encased in a cuticular exoskeleton and are thought to bend only between segments or subsegments where the cuticle is thinner, more flexible, or bent into a fold. There is a growing appreciation of the dominating influence of folds in the mechanical behavior of a structure, and the bend...

The purpose of this paper is to propose a method for testing the effect varying kerfing parameters, on flexibilization plywood panels indoor applications. evaluation was made by comparisons change in MOE, MOR, and maximum deflection, between flexibilized non-flexibilized specimens subjected static bending tests based EN 310. In order prevent problem sliding from supports occurring specimens, st...

Metal magnetic memory (MMM) is a widely used non-destructive electromagnetic detection technology. However, the analysis of its underlying principle still insufficient. The mechanical and coupling model reasonable standpoint from which to study MMM. In this paper, steel material established based on density functional theory (DFT) using CASTEP first-principles software. order simulate practical...

This paper deals with the threshold radius that warrants the use of single restraining rail for transit and railroads. Different railways use different threshold radius from 91m to 365m to provide restraining rail. These threshold figures are probably experience driven choices. The need for restraining rail may be related to a so-called derailment alarm coefficient of 1.2 sustained over 2m leng...

7 This paper proposes a three-stage game-theoretic model to study air-rail competition in intercity 8 passenger corridors. We consider duopolistic markets, in which a rail agency competes against an airline to 9 maximize their respective objectives. The objective of the rail agency can be maximizing profit or social welfare, 10 or a mix of the two. At the top stage, the rail agency first determ...

bending analysis of multilayer graphene sheets (mlgss) subjected to non-uniform shear and normal tractions is presented. the constitutive relations are considered to be non-classical based on nonlocal theory of elasticity. based on the differential transformation method, numerical illustrations are carried out for circular and annular geometries. the effects of nano scale parameter, radius of c...

in this paper, a closed form solution for bending and free vibration analyses of simply supported rectangular laminated composite plates is presented. the static and free vibration behavior of symmetric and antisymmetric laminates is investigated using a refined first-order shear deformation theory. the winkler–pasternak two-parameter model is employed to express the interaction between the lam...
