Abstract: | The theory of thermoelasticity with energy dissipation is employed to study plane waves in a fibre-reinforced anisotropic
thermoelastic half-space. We apply a thermal shock on the surface of the half-space which is taken to be traction free. The
problem is solved numerically using a finite element method. Moreover, the numerical solutions of the non-dimensional governing
partial differential equations of the problem are shown graphically. Comparisons are made with the results predicted by Green–Naghdi
theory of the two types (GNII without energy dissipation) and (GNIII with energy dissipation). We found that the reinforcement
has great effect on the distribution of field quantities. Results carried out in this paper can be used to design various
fibre-reinforced anisotropic thermoelastic elements under thermal load to meet special engineering requirements. |
