Free vibration analysis of graphene sheets on elastic matrix

Graphene sheets are generally surrounded by an elastic matrix in applications. In the present study, freevibration analysis of graphene sheets is investigated via higher-order elasticity theory. Graphene sheet ismodeled via thin plate on elastic medium. Winkler-Pasternak two-parameter elastic foundation model is usedas foundation. The method of modified couple stress theory is used for size-dependent vibration. Frequencies have been calculated by discrete singular convolution and analytical method.
