... ABSTRACT Any catastrophic rupture scenarios of a steel pipe should be taken into considerations in the design and during the maintenance stage as the loss-of-containment may be accompanied by either property damage or fatal accidents. Ductile fracture of wrinkled (buckled) steel pipes...

... ABSTRACT The influence of a pipe's internal pressure on the critical strain at rupture and on ductile crack propagation is investigated. Full-scale tensile tests and a finite-element analysis (FEA) were conducted, with and without internal pressure, using full-scale pipes with surface notches...
