In the present paper, a novel unconstrained higher-order theory (UCHOT) is applied to analyse free vibration of cylindrical sandwich shells with nanocomposite face sheets reinforced graphene platelets. UCHOT considers shear and thickness deformations. It assumed that cylinder includes soft core which embedded between functionally graded platelets composites (FG-GPLRC). FG-GPLRC sheet consists s...

In this article, dynamic modeling of double walled cylindrical functionally graded (FG) microshell is studied. Size effect of double walled cylindrical FG microshell are investigated using modified couple stress theory (MCST). Each layer of microshell is embedded in a viscoelastic medium. For the first time, in the present study, has been considered, FG length scale parameter in double walled c...

Rubber belt not only is one of the key components of belt conveyor, but also affects the overall performance of the core part. Research on dynamics analysis of large conveyor not only helps to improve the reliability and design level, but also can guide the rational selection of conveyor safety factor, and effectively reduce the cost of the conveyor belt. Based on unique viscoelastic properties...

In this study, the effects of laser light on heat transfer a thin beam heated by an applied current and voltage are investigated. Laser heating pulses simulated as endogenous sources with discrete temporal properties. The conduction equation is developed using energy conservation modified Moore–Gibson–Thompson (MGT) flow vector. Thermal structural analysis Euler–Bernoulli microbeams provided su...

The dynamical responses of railway track has been carried out by different ways. In this work, developing an analytical model for the ballasted which includes two rails connected to sleeper, a fast method calculated dynamic is presented. rail modelled as infinite beams posed on periodically supports are rested viscoelastic foundation. We consider equation in steady-state subjected moving loads....
