abstract

in this paper, on the basis of a new strain gradient elasticity theory, wave propagation in rectangular nanoplates by considering in-plane magnetic field is studied. this strain gradient theory has two gradient parameters and has the ability to compare with the nonlocal elasticity theory. from the best knowledge of author, it is the first time that this theory is used for investigating wave propagation in nanoplates. it is also the first time that magnetic field is considered in modeling the wave propagation in rectangular nanoplates. in this article, an analytical method is adopted to achieve an exact solution for the governing equation. to verify the present methodology, our results are verified with the results published by present authors and other researchers. it is obtained that with the increase of static gradient parameter, the frequencies are increase. it is also shown that the phase velocities increase for the increase of magnetic field.

Static analysis of rectangular nanoplates using trigonometric shear deformation theory based on nonlocal elasticity theory

In this article, a new higher order shear deformation theory based on trigonometric shear deformation theory is developed. In order to consider the size effects, the nonlocal elasticity theory is used. An analytical method is adopted to solve the governing equations for static analysis of simply supported nanoplates. In the present theory, the transverse shear stresses satisfy the traction free...

Variational Principle and Plane Wave Propagation in Thermoelastic Medium with Double Porosity Under Lord-Shulman Theory

The present study is concerned with the variational principle and plane wave propagation in double porous thermoelastic infinite medium. Lord-Shulman theory [2] of thermoelasticity with one relaxation time has been used to investigate the problem. It is found that for two dimensional model, there exists four coupled longitudinal waves namely longitudinal wave (P), longitudinal thermal wave (T),...
