The present investigation deals with the study of two-dimensional fundamental
solution in orthotropic piezothermoelastic diffusion media. By virtue of the two-dimensional
general solution of orthotropic piezothermodiffusion elastic media, the fundamental solution
for a point heat source and chemical potential source on the surface of a semi-infinite
orthotropic piezothermoelastic diffusion plane is constructed by five newly introduced
harmonic functions. The components of displacement, stress, electric displacement, electric
potential, temperature change and chemical potential are expressed in terms of elementary
functions. The components of displacement, electric potential, temperature change and
chemical potential are computed numerically and depicted graphically. From the present
investigation, a special case of interest is also deduced to depict the effect of diffusion.
