a 5th order shear deformation theory considering transverse shear deformation effect as well as transverse normal strain deformation effect is presented for static flexure   analysis of simply supported isotropic plate. the assumed displacement field accounts for non-linear variation of in-plane displacements as well as transverse displacement through the plate thickness. the condition of zero ...

A revised procedure for the design of steel plate shear walls is proposed. In this procedure, the thickness of the infill plate is found using equations that are derived from plastic analysis of the strip model, which is widely accepted for the representation of steel plate shear walls. Equations are derived from a basic steel plate shear wall configuration but are shown to be conservative for ...

Previous research has hinted on further improvements of the buckling behaviour variable-stiffness laminates by incorporating overlaps, resulting in a variable thickness profile that is non-linearly coupled to steering angles. The present study compares two modelling strategies consider distribution: 1) as-manufactured with discrete thicknesses; and 2) smoothed continuous distribution. created o...

composite couple beams are the concrete elements consisting of longitudinal bars and steel plate, therefore suitable for shear transferring in couple shear walls with arranged gates in its height. in this paper, after modeling couple beams with and without steel plates with f.e methods and calibration the models with experimental results, effects of parameters such as thickness, height, length ...

Effects of diffusion induced stress on the hydrogen absorption into plate form electrodes of b-phase PdHx are discussed numerically based on the Volmer–Tafel route of the hydrogen evolution reaction, and thermodynamic considerations involving stress fields and non-ideal interactions of hydrogen in the electrode. It is found that the self-induced stresses enhance the absorption rate and may exce...

A new reflecting surface capable of simulating identical reflecting properties of a metallic plate with rectangular corrugations is reported. The new surface which is fabricated with a low loss dielectric plate of uniform thickness .One surface of the plate is periodically loaded with a grill structure of conducting wires and the other surface is completely metalized with copper. Depending on t...

The structure of the solution of the Reissner–Mindlin plate equations is investigated, emphasizing its dependence on the plate thickness. For the transverse displacement, rotation, and shear stress, asymptotic expansions in powers of the plate thickness are developed. These expansions are uniform up to the boundary for the transverse displacement, but for the other variables there is a boundary...

Abstract. The Reissner-Mindlin plate theory models a thin plate with thickness t. The condition numbers of finite element approximations of this model deteriorate badly as the thickness t of the plate converges to 0. In this paper, we develop an overlapping domain decomposition method for the Reissner-Mindlin plate model discretized by the Falk-Tu elements with the convergence rate which does n...

for fighting with blights and studying on effect of thickness, two experiments were done. the first series were included independent variable ages of blight in four levels (age1,age2,age3 and age4) and the thermal care temperature in four levels(10,15,20 and 30 seconds) and the dependent variable is death rate . the second series were included independent variables thermal care temperature in t...

In this paper, a rectangular sandwich plate with a constrained layer and an electrorheological (ER) fluid core is investigated. The rectangular plate is covered an ER fluid core and a constraining layer to improve the stability of the system. The two outer layers of the sandwich structure are elastic. The viscoelastic materials express the middle layer behavior under electric field and small st...
