Axisymmetric bending of functionally graded circular and annular plates

Axisymmetric bending and stretching of functionally graded solid and annula r circular plates is studied using the first-order shear deformation Mindli n plate theory. The solutions for deflections, force and moment resultants of the first-order theory are presented in terms of the corresponding quant ities of isotropic plates based on the classical Kirchhoff plate theory. Th is gives the Mindlin solution of functionally graded circular plates whenev er the Kirchhoff solution to the problem is known. Numerical results for di splacements and stresses are presented for various percentages of ceramic-m etal volume fractions. (C) Elsevier, Paris.
