The oscillation of thermal stratification layer has possibilities to induce thermal fatigue damages on structures of nuclear components. To evaluate thermal stress induced by thermal stratification oscillation, the moving layer frequency response function of thermal stress was developed. However, the model assumed in developing this function does not take into account the thickness of the thermal stratification layer. Thus, It is impossible to evaluate the stress generated by thermal stratified layer having finite thickness with sufficient accuracy. To clarify the effects of thickness of stratified layer, finite element simulations were conducted under some fluid conditions. Based on mechanisms of above effects, the frequency response function was improved.
