Analysis of wave motion in micropolar plate possessing cubic symmetry

Kumar R., Partap G.

International Journal of Applied Mechanics and Engineering

Vol. 14, no 2

403-414

The present paper concentrates at studying the analysis of wave motion in a homogenous isotropic micropolar plate possessing cubic symmetry. The upper and lower surfaces of the plate are subjected to stress free conditions. The frequency equations for symmetric and skewsymmetric wave modes of propagation are derived. The amplitudes of displacement components and microrotation are also computed and presented graphically during the symmetric and skewsymmetric motion of the plate. Finally, in order to illustrate and verify the analytical developments, numerical solution of frequency equation corresponding to stress free micropolar cubic crystal plate is carried out for magnesium crystal material and represented graphically. The results of phase velocity, displacements and microrotation have been compared for micropolar cubic crystal plate and micropolar elastic plate and illustrated graphically.
