Research Conducted at Islamic Azad University Has Provided New Information about Low Dimensional Structures (Decoupling the nonlocal elasticity equations for thermo-mechanical vibration of circular graphene sheets including surface effects)

By a News Reporter-Staff News Editor at Physics Week -- Current study results on Low Dimensional Structures have been published. According to news originating from Tehran, Iran, by VerticalNews correspondents, research stated, "This article deals with the axisymmetric vibration properties of circular single-layered graphene sheet embedded in a polymer matrix under thermo-mechanical loading. Both surface and nonlocal effects are taken into account."

Our news journalists obtained a quote from the research from Islamic Azad University, "To this end, Gurtin-Murdoch continuum elasticity in conjunction with the nonlocal elasticity theory is used to develop a modified continuum plate model for free vibration analysis of the nanoplates. The governing equations are derived by decoupling the nonlocal constitutive equations of Eringen theory in the polar coordinate. Galerkin's method is used to obtain the vibration frequencies. To verify the accuracy of the Galerkin results, a differential quadrature (DQ) solution is also developed. Galerkin results are successfully verified with those of the DQ method. A good agreement is also found between the present results and experimental data."

According to the news editors, the research concluded: "Further, in comparison to the available molecular dynamics simulation results, the present formulation with appropriate values of surface and nonlocal parameters provides more accurate results than those by the classical plate model."
