The stress solution can be obtained by superposing the stress disturbance by the crack on the transient thermal stresses due to the heat source in an infinite plate with a circular hole. The problem is reduced to a singular integral equation which satisfies the boundary condition on the crack face. The numerical results of stress intensity factors are obtained for the case of a uniformly distributed heat source and a small crack. The effects of the location of the heat source on the variations of stress intensity factors are considered.
