The harmonic function techniques are used. The thermal stresses, temperature and displacement have been obtained. These expressions are calculated numerically for two values of elastic constants for mediums M1 and M2 respectively. The results obtained are displayed by graphs to clear the phenomena physical meaning. The results indicate that the effect of gravity, relaxation times and parameters of fibre-reinforced of the material medium are very pronounced.展开更多
