  The equations governing the thermoelastic-plastic flow of isotropic solids in
the Prandtl-Reuss and small anisotropy approximations in Cartesian coordinates
are generalized to arbitrary coordinate systems. In applications the choice of
coordinates is dictated by the symmetry of the solid flow. The generally
invariant equations are evaluated in spherical, cylindrical (including
uniaxial), and both prolate and oblate spheroidal coordinates.
