The solution of the problem of static radial deformation of a piezoelectric spherical shell, polarized in the radial direction corresponding to uniform pressures on the inner and outer surfaces of the shell, and a given voltage difference between these surfaces, coupled with a radial distribution of temperature from the inner to the outer surface, forms the chief interest of the present note. The constitutive relations, deduced by Mindlin are taken in a form which closely resemble those of Toupin.
