..., and the decreasing load is recorded. Scanning electron microscopy can be used to verify the presence of brittle cracking typical of hydrogen-embrittlement-type failures (i.e., flat facets instead of dimpled rupture). Conventional test methods include the cantilever beam, wedge-opening load, contoured double...

A test for the discrimination of surface preparations finally became available with the development of the wedge-opening (double- cantilever beam). In general, high-performance structural adhesive bonding...
