A neutron diffraction study of local stress concentrations surrounding defects in pipeline steel

Changes in lattice-strain profiles around a fatigue crack through the retardation period after overloading

“…Neutron diffraction is a nondestructive method [3] that is useful for the study of the overload effects by mapping the elastic internal strains around the crack tip. Previously a compressive lattice-strain profile was clearly observed ahead of a fatigue-crack tip after an overload using neutron diffraction [4].…”

Dynamic response of a partially debonded pipeline embedded in a saturated poroelastic medium to harmonic plane waves

“…Therefore, maintaining its structural integrity and reliability is essential to the world's energy requirements. In order to improve the safety performance of the natural gas pipeline supply system, the stress analysis including mechanical damage [2][3][4] and stress concentration [5] was widely carried out.…”
