| Abstract: | Safety assessment methods relating to the pressure piping with defects are various; including mainly the plastic failure criteria for control of limit load,J-integral in fracture mechanics method,a well-known engineering safety assessment procedure R6 in British, America ASME standard assessment method, uncertain paramneters defects assessment method and so on. These methods were reviewed and summarized;some difference and relations were analyzed. Meanwhile, the developmental trend of its engineering, reliability and intelligence was also presented for the safety assessment methods of pressure piping with defect. |
