Abstract

Axisymmetric bending response of shear deformable cylindrically orthotropic circular plates under the action of uniform transverse pressure is investigated by means of the differential transform method (DTM). Due to its simplicity, DTM has been one of the widely used numerical techniques in the solution of boundary value problems and initial value problems. Since DTM provides a series expansion, the accuracy of the results obtained by DTM depends highly on the number of terms considered in the solution. The formulation used in this computational study is based on the first order shear deformation theory (FSDT). The governing equations include three field variables which are the deflection, the horizontal radial displacement, and the rotation. Numerical simulations are performed to study the bending behavior of the plate which is in contact with a two-parameter elastic medium. The influence of the material properties, and the effect of the elastic foundation on the maximum deflection are discussed. The accuracy of the results obtained in the current study is validated through comparison study.
