摘要：

A J-resistance curve solution is developed for a circumferential throughwall crack in a pipe under combined bending and tension. The J solution can be applied with load-displacement-crack extension data from one pipe test. Material resistance curves are developed for throughwall cracks in Type-304 stainless steel and SA333 Gr6 carbon steel base materials. The effect of loading type on the J-resistance curve is shown to be insignificant. Post-test tearing instability analyses are performed to assess the accuracy of J-estimation scheme solutions and conservatism associated with the use of a specimen J-resistance curve.
