Analysis of full-scale burst tests by FE modelling using constant CTOA fracture criterion

Analysis of full-scale burst tests by FE modelling using constant CTOA fracture criterion

Several backfilled full-scale burst tests were recently performed by TC Energy on CSA Z245.1 Grade 550 Category II pipe steels. This paper presents a new interpretation of the recent full scale burst test data using the crack tip opening angle (CTOA) as fracture propagation criterion. ASTM E3039 was...
