Functionally graded porous (FGP) plates have been introduced as modern structural members which open a new window to optimal and functional designs. Despite the need study effect of porosity on mechanical behavior FGP plates, it is necessary consider very extensive valuable literature in this field, presenting remarkable closed-form solutions. Hence, paper aims answer where possible implement a...

Abstract The stability behaviour of unsymmetrical laminated structures made fibre-reinforced plastics is significantly influenced by bending–extension coupling and the comparatively low transverse shear stiffnesses. aim this work to improve analytical analysis unsymmetrically structures. With discrete plate theory, can be reduced single plates. structure divided into individual segments, surrou...

geometric and material nonlinear behavior of slender webs in i-column girders having stocky flanges under the action of combined lateral and axial loads is investigated. interaction curves corresponding to the application of compressive and shear loads at buckling and ultimate stages for both web plates and column sections are plotted. in addition, the effects of flange and web slenderness rati...

this paper has focused on vibration and buckling of thin rectangular plates when at least two opposite sides are simply supported condition and subjected to axial and biaxial initially stresses. analysis is based on exact solution method, without further usage of any approximate method. first analytic techniques are used to discuss the free vibrations of plate. then, natural frequencies and cri...

In this paper, we propose a novel and efficient differential quadrature element based on Lagrange interpolation to solve a sixth order partial differential equations encountered in non-classical beam theories. These non-classical theories render displacement, slope and curvature as degrees of freedom for an Euler-Bernoulli beam. A generalize scheme is presented herein to implementation the mult...

Soil-water characteristic curve (SWCC) correlates the water content of a soil to its suction, which is very important property unsaturated soils. Osmotic tensiometers (OTs) have shown their capability in high suction measurement. This study tried use OT combined with pressure plate and WP4C dewpoint potentiometer determine SWCC residual soil. Three OTs different measuring ranges (900 kPa, 1200 ...
