On the Axisymmetric Thermoelastic Problem in Bispherical Coordinates

Abstract

Results of the thermoelastic analysis of an infinite elastic medium containing two arbitrary-sized spherical cavities with arbitrary separation distance are presented graphically. Of particular interest is the interference effect of one cavity on the other. The cavity surfaces are assumed to be held at uniform temperature while zero temperature prevails at infinity. Examples treated include those for which the cavity surfaces are stress-free and those for which individually self-equilibrated rigid liners are bonded to the cavity surfaces.
