this paper presents a clear monograph on the optimization of thermal instability resistance of the fg (functionally graded) flat structures. for this aim, two fg flat structures, namely an fg beam and an fg circular plate, are considered. these structures are assumed to obey the first-order shear deformation theory, three-parameters power-law distribution of the constituents, and clamped bounda...
Nonlinear behavior of a functionally graded cantilever beam is analyzed under non-uniform hygro-thermal effect. To solve this problem, finite element method is applied within plane solid continua. Total Lagrangian approach is utilized in the nonlinear kinematic relations. Newton-Raphson method with incremental displacement is used in nonlinear solution. Comparison study is performed. Effects of...
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...
In this study, the feasibility of using Lamb waves in functionally graded (FG) nano copper layered wafers nondestructive evaluation is evaluated. The elastic parameters and mass densities these vary with thickness due to variation grain size. power series technique used solve governing equations variable coefficients. To analyze multilayered structures, which material are continuous but underiv...
In this paper, an investigation of linear eigenvalue buckling functionally graded material (FGM) plates under uniaxial loading is carried out. The computer model analyzed using the finite element (FE) package ABAQUS. An analysis out to study effect size and geometry openings in FGM plate on critical load. circular, square, diamond vary based ratio opening diameter width plate. Moreover, aspect ...
