Recent development in low-constraint fracture toughness testing for structural integrity assessment of

Jidong KANG, James A. GIANETTO, William R. TYSON

Frontiers of Mechanical Engineering 2018, Volume 13, Issue 4,   Pages 546-553 doi: 10.1007/s11465-018-0501-2

Abstract:

Fracture toughness measurement is an integral part of structural integrity assessment of pipelinesSuch a test provides high constraint and therefore conservative fracture toughness results.Low-constraint toughness tests represent more realistic loading conditions for girth weld defects, andthe corresponding increased toughness can minimize unnecessary conservatism in assessments.Examples are also given of the integration of fracture toughness data from SE(T) tests into structural
