Jp. Zhao et al., A NEW CONCEPT - PROBABILISTIC FAILURE ASSESSMENT DIAGRAM, International journal of pressure vessels and piping, 71(2), 1997, pp. 165-168
In this paper a new concept, the probabilistic failure assessment diag
ram (p-FAD), is put forward, and the technology of p-FAD has been carr
ied out for defect assessment. The methodology of p-FAD is a new appro
ach for defect assessment in which probabilistic parameters were intro
duced and with which the probabilistic safety assessment can be carrie
d out during the procedure of failure assessment. Based on the EPRI me
thodology, the engineering approach for elastic-plastic fracture analy
sis, the stochastic analysis of the J integral was calculated and then
the statistical characteristic of the J integral was performed. (C) 1
