Recently, the stability calculation of functionally graded (FG) plate has attracted many scientists, especially when considering FG with cracks. In this work, is made from a new generation composite material consisting two components, ceramic and metal, law continuous exponential distribution. The placed on Winkler - Pasternak elastic foundation background parameters. Then, we used third-order ...

optimal conditions are used in nondynamical formalism to diagonalize the pionproton reaction matrix as much as possible. invariance laws are imposed to simplify the relationship between observables and bilinear combination of amplitudes. transverse amplitudes are determined by using measured polarization parameter in xfp elastic scattering at 6.0 gevic

In this research, analysis of nonlocal magneto-electro-thermo-elastic of a functionally graded nanobeamdue to magneto-electro-elastic loads has been done. In order to formulate the problem the Timoshenko theory of beams is utilized. The principle of virtual work, Hamilton’s principle as well as nonlocal magneto-electro-thermo-elastic relations has been recruited to derive the governing eq...

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...

Shallow foundations in granular soils are designed such that the settlements are within tolerable limits. Schmertmann’s (1970) method is one of the most rational methods for computing settlements of footings in granular soils, and is commonly used world-wide. The method relies on a strain influence factor that varies with depth. Schmertmann et al. (1978) proposed separate strain influence facto...

Under the influence of axial forces and uniform temperature variations, thermal buckling postbuckling composite beams reinforced functionally graded multilayer graphene platelets (GPLs) resting on nonlinear elastic foundations are examined. The Halpin-Tsai model is used to calculate modulus each layer GPL-reinforced (GPLRC). According virtual work principle, governing equations for beam obtaine...
