In this present study, we are interested in the use of a precise theory shear deformation for buckling analysis plates with functional gradation simply supported such as refined four variables. Several parameters comparison have been used, dimensional and nondimensional. The displacement field is compatible nonuse correction factors satisfied, choice material very way variable according to thic...

This paper presents a new finite modelling of the nonlinear static bending analysis piezoelectric functionally graded (FG) sandwich plates resting on elastic foundations. Finite element formulations are derived by using first-order shear deformation theory (FSDT) Mindlin and method. The proposed mathematical model this work verified comparing results with those other methods, they in good agree...

The modern engineering structures require the advanced engineering materials to resist the high temperatures and to provide high stiffness. In particular the functionally graded porous materials (FGPMs) introduced are expected to have these desired properties, consequently eliminating local stress concentration and de-lamination. In the present paper, a new shear strains shape function is chose...
