Sensitivity Analysis of Failure Probability on PTS Benchmark Problems of Pressure Vessel Using a Probabilistic Fracture Mechanics

摘要

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
