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.
