abstract

Regarding of structures behaviour which can be found in nuclear reactor, most of assessment method are based on the valuation of parameter J. This paper deals with the J calculation in cracked elbows submitted to internal pressure and various bending moments. Recent works on elbows including a semi-elliptical defect performed in the frome of the A16 guideline improvements are presented. The A16 methodology is based on the reference stress concept (named CEP method): It consists in an amplification of the elastic value of J by a plastic correction deduced from the reference stress. The elastic value of J is deduced from the influence factors of the pipe and from analytical relations for elastic nominal stresses. The reference stress estimation is performed using two equivalent stresses corresponding to the elastic and plastic behaviours of the cracked component. The analytical relations for the elastic value J and the reference stress determinations are presented and validated using 3D FE calculations.
