Abstract |
|
|
| This paper concentrates on the study of propagation of waves in a homogenous isotropic
micropolar thermoelastic plate possessing cubic symmetry subjected to stress free
boundary conditions in context of Lord and Shulman (L-S) and Green and Lindsay
(G-L) theories of thermoelasticity. The secular equations for homogeneous isotropic
micropolar thermoelastic plate possessing cubic symmetry for symmetric and skew
symmetric wave modes of propagation are derived. The amplitudes of displacement
components, microrotation and temperature distribution are also computed during the
symmetric and skew symmetric motion of the plate. Finally, in order to illustrate and
verify the analytical developments, numerical solution of secular equation corresponding
to stress free thermally insulated micropolar thermoelastic cubic crystal plates is
carried out for magnesium crystal material. |
