A pre-existing surface cracked stainless steel specimen is brought to light to the cyclic temperature of convective medium. The history of cracked body’s stress intensity factor (SIF) is obtained by using appropriate weight function method is presented in this paper. Numerical simulation is performed with FEM based software ABAQUS. Cyclic temperature induces the compressive and tensile stresses in the specimen which in turn becomes the main cause of cyclic fatigue in the specimen. The other intensity function of body induced stress is stress intensity. The result shows that the behavior of Fatigue does not based only on the temperature range but also on frequency, Biot number and Initial temperature of the specimen.
