▎ 摘　　要

Graphene sheets are generally surrounded by an elastic matrix in applications. In the present study, free vibration analysis of graphene sheets is investigated via higher-order elasticity theory. Graphene sheet is modeled via thin plate on elastic medium. Winkler-Pasternak two-parameter elastic foundation model is used as foundation. The method of modified couple stress theory is used for size-dependent vibration. Frequencies 10.17341/gazimmfd. 322182 have been calculated by discrete singular convolution and analytical method.
