scope:

With this test method, the flexural fatigue life for any given bend radius, the flexural fatigue behavior, and the ductility of the metal cladding in percent deformation after tensile failure can be determined.

Note: The indirect determination of cladding ductility by using a fatigue test is made necessary by the geometry and dimensions of foil samples, which make tensile elongation and rupture tests inadequate for ductility determination.

Note: Processing may change the original mechanical properties of the conductor metal.
