A plane-stress thermoelastic problem in a nonhomogeneous rectangular region with a circular hole subjected to transient heating on the circular hole has been formulated by the stress function method. The system of fundamental equations obtained has been solved numerically by the finite difference method. To analyse numerically the plane-stress thermoelastic problem in the non-homogeneous region, with two distinct boundary geometries, by the use of the less number of grids, we introduce two types of finite difference grid parallel to each co-ordinate curve of rectangular co-ordinate and polar co-ordinate systems. Numerical calculations are carried out for the thermal conductivity, Young's modulus and the coefficient of linear thermal expansion which vary exponentially with the distance from the co-ordinate origin.
