Abstract |
|
|
| The present paper is aimed at studying the effect of gravity on the general model of the equations of the generalized thermomicrostretch
for a homogeneous isotropic elastic half-space solid whose surface is subjected to a Mode-I crack problem. The problem
is in the context of the Green and Naghdi theory (GN). The normal mode analysis is used to obtain the exact expressions for the
displacement components, the force stresses, the temperature, the couple stresses and the microstress distribution. The variations of the
considered variables through the horizontal distance are illustrated graphically. Comparisons are made with the results in the presence
and absence of gravity with two cases: Case (1) for the generalized micropolar thermoelasticity elastic medium (without microstretch
constants) between the both types (II, III). Case (2) for the generalized micropolar thermoelasticity elastic medium (without micropolar
constants) between the both types II and III. |
