An axisymmetric elastic analysis for circular sandwich panels with functionally graded cores

摘要: Abstract This paper presents an analytical solution in the framework of elasticity theory, which is useful describing elastic bending response axisymmetric circular sandwich panels with functionally graded material cores and homogeneous face-sheets. The Young’s modulus core assumed to be exponentially dependant on transverse direction Poisson’s ratio as well uniform equal face-sheets ratio. obtained using a Plevako representation, reduces problem search potential functions satisfying linear fourth-order partial differential equations. We explicitly obtain by writing Fourier Bessel expansions respect radial coordinate. A comparative study versus presented considering first term expansion loading condition. In this way, written closed form furnishes benchmark accurately investigate agreement structural theory results.
