| Abstract: | Based on the EPRI J-estimation handbook and elastic-plastic finite element solution,failure assessment curves (FAC) of EPRI nozzle 2-dimensional model and crack emanated from a center elliptical hole for materials of A533B and 16MnR have been derived respectively .By comparison of the derived curves with option 2 curve of R6-Revision 3,the suitability of option 2 FAC of R6 for crack locating in high strain zone has been discussed. |
