... is determination of strain. The most direct, reliable method uses electrical resistance strain gages. The frequency response capability of strain gages is considerably greater than the mechanical response of the combination of load train, specimen, and load cell. Another method of measuring strain involves...

... is the preferred method for detecting surface-breaking and, under certain circumstances, near-surface flaws in situations where a test material can be magnetized. This method depends on the flaw disrupting the magnetic flux generated along the surface of the weld by a permanent magnet or electromagnets...
