Abstract: The propagation of circularly crested the rmoelasticd iffusive waves in an infinite homogeneous transversely isotropic plate subjected to stress free,isothermal/insulated and chemical potential conditions was investigated in the framework of different theories of thermoelastic diffusion.The dispersion equations of therm oelastic diffusive Lamb type waves were derived'some special cases of dispersion equation were also deduced.
