چکیده

Research to build a filter to prevent harmful substances from entering the body has been considered recently in the science of nanomedicine. In order to achieve this goal, in this research low-velocity impact of nano germs on visco-elastic orthotropic graphene sheet(VOGS) as a nanomedicine filter has been studied using third-order shear deformation theory. The viscoelastic material is modeled by Kelvin-Voigt theory.Based on Hamilton's principle and the nonlocal theory the equations of motion are derived. VOGS is embedded in viscoelastic medium as a washer which is simulated by visco-Pasternak foundation model. Results of a detailed parametric show that the effects of nonlocal parameter, structure damping and elastic modulus of nano germs have great effect on lateral deflection of nano filter.It is hoped that the results of this analysis are used in the manufacture of nano medicine
