A point heat source on the apex of a transversely isotropic piezothermoelastic cone

We use the compact harmonic general solutions of transversely isotropic piezothermoelastic materials to construct the three-dimensional solutions of a steady point heat source on the apex of a transversely isotropic piezothermoelastic cone by four newly introduced harmonic functions. All components of coupled field are expressed in terms of elementary functions and are convenient to use. When the apex angle 2α equals to π, the solutions reduce to those of the semi-infinite body problem, which is called Greenʹs function. Numerical results are given graphically by contours.
