hydrogen embrittlement


condition of low ductility or reduced mechanical properties resulting from the absorption of hydrogen


  • NOTE stress intensity factor, K factor describing the stress state near the tip of a crack caused by a remote load, residual stress or both.
  • NOTE The magnitude of K depends on sample geometry, the size and location of the crack, and the magnitude and the modal distribution of loads on the material. where: a half the crack length K stress intensity factor Y dimensionless geometrical function s applied stress
