Abstract : The investigation deals with the stress distribution in microfibers engaged in a steady state heat transfer with a discontinuous surface temperature distribution. The microfibers studied were free from any mechanically provocative boundary restraints. The exact theories of the thermoelastic potential and of Boussinesq displacement potentials have been used to investigate two-dimensional and three-dimensional cases. In two-dimensional cases (plane strain) no infinite stress is induced but in a cylindrical microfiber the stress becomes logarithmically infinite at places where the surface temperature has a jump discontinuity.
