In this paper, the effect of elastic foundation on the out of plane displacement of functionally graded circular plates using differential transform method is presented. Differential transform method is a semi-analytical-numerical solution technique that is capable to solve various types of differential equations. Using this method, governing differential equations are transformed into recursiv...

Third order shear deformation theory of cylindrical shells is employed to investigate the vibration characteristics of non-homogeneous cylindrical shells surrounded by an elastic medium. The kinematic relations are obtained using the strain-displacement relations of Donnell shell theory. The shell properties are considered to be dependent on both position and thermal environment. A suitable fun...

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...

this work presents thermoplastic analysis of fg rotating diskswith variable thickness and constant angular velocity. the solutions are obtained by variable material property (vmp) theory. in this theory, the domain is divided into some finite sub-domains in the radial direction, in which the properties are assumed to be constant and the form of the elastic response is used to solve elastic-plas...

the changes in viscoelastic properties of potatoes (tubuls agria) stored at 4 ˚c for 4 months were modeled and evaluated by using the creep-recovery test. cylindrical specimens with 15 mm in diameter and 35 mm long were used. the samples were allowed to deform gradually under the constant stress (110 kpa) for about 30 min. after removing the load, the sample recovery was registered. deformation...

The mechanical properties including elastic stiffness constants as well as bulk modulus of Palladium (Pd) nanowire were calculated in the constant temperature and pressure (NPT), ensemble by molecular dynamics (MD) simulation technique. The quantum Sutton-Chen (Q-SC) many-body potential was used to calculate the cohesive energy as well as forces experience by every atoms. The temperature and pr...
