in this study, forced-vibration analysis of a coupled system of single layered graphene sheets (slgss) subjected to the moving nano-particle is carried out based on nonlocal elasticity theory of orthotropic plate. two slgss are coupled with elastic medium which is simulated by pasternak and visco-pasternak models. using hamilton’s principle, governing differential equations of motion are derive...

Abstract In the study, poly(methyl methacrylate) (PMMA)/zircon (ZrSiO 4 ) composites were successfully prepared using liquid method at different compositions of 1, 2.5, and 5 wt% zircon. The zircon filler was processed from a natural, local sand via top-down wet ball-milling for 15 h as well annealing temperature 200 °C 1 h. force-displacement curves have been acquired DMA (dynamic mechanical a...
