摘要

This report is a continuation of the initial development work towards the single specimen J integral determination for Koeberg pressure vessel steel and aims to help clarify the reproducibility and sensitivity of firstly the multiple specimen COD technique and secondly the multiple specimen J integral techniques using a medium strenght steel. The objective of this present study was to consolidate work already done which effectively measured initiation COD in Roqtuff material, by repeating COD tests and concomitantly estimating the corresponding J integral values.
