- 論文の詳細を見る
In this paper, the results of the sensitivity analyses of failure probability are presented for pressure vessel under PTS (Pressurized Thermal Shock) transient, by using our new probabilistic fracture mechanics analysis code. The pressure, the fluid temperature at the inner surface of pressure vessel and other analysis conditions are based on an international benchmark study on PTS. The temperature and stress distributions through wall thickness during transient are obtained by a heat transfer and an elasto-plastic stress analysis with FEM. The new models and methodologies introduced in our code are summarized and the effect of overlay clad and behavior of semi-elliptical crack on the failure probability are investigated especially.
