A plane-stress thermoelastic problem in a multiply connected region of variable thickness is formulated in terms of a stress function by deriving new Michell integral conditions necessary for the assurance of single-valuedness of rotation and displacements. The system of fundamental equations is solved by means of a finite difference method and numerical calculations are carried out for the cases of a rectangular plate of variable thickness with a rectangular hole.
