This paper analyzes how to realize fast calculation when thermal stratification effect is considered in fatigue monitoring system.A new Green's function considering thermal stratification effect is proposed.At the same time,the thermal stratification stress of elbow model under assumed transient state is calculated by this method and compared with the finite element method,which shows that this method is reasonable and accurate.The results show that the calculation method based on Green's function and considering thermal stratification is efficient,fast and accurate,and can be applied to the stress servere position at the corner of elbow.At present,the method has been applied to the fatigue monitoring system of nuclear power plant equipment.
