Abstract
The article introduces a new continuous element (CE) for free vibration analysis of stepped functionally graded materials (FGMs) annular plates having non-homogenous material properties and varying thickness subjected to arbitrary boundary conditions. By applying the powerful assembly capacity of CE method, the dynamic stiffness matrix for the stepped FGMs annular plates with non-homogenous properties has been established. Continuous Element Method allows computing the natural frequencies with high accuracy for any frequency range where almost other current methods meet grand difficulties due to the number of meshing elements. Using minimum meshing for complex structures, this model accelerates the speed of computation and economies the storage capacity of computers.
