FURTHER INVESTIGATIONS ON THE RELATIONSHIP BETWEEN INTERNAL DAMPING AND SUSCEPTIBILITY TO STRESS CORROSION CRACKING

The experimental procedure developed by Hochrein and Thiruvengadam and further modified as reported in the report is an elegant tool for determining susceptibility to stress corrosion cracking. Susceptibility can be detected long before any microscopic evidence of cracking becomes noticeable. This procedure is adaptable to different shapes and thicknesses of materials, and further development would lead to a compact, portable nondestructive test instrument to be used in testing aircraft wings, ocean structures, etc., in the field.
