ASTM C394 Standard Test Method for Shear Fatigue of Sandwich Core Materials

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ASTM C394 testing. This test method determines the effect of repeated shear forces on the core material used in sandwich panels. Allowed core material forms include those with continuous bonding surfaces (such as balsawood and foams) as well as those with discontinuous bonding surfaces (such as honeycomb).

This test method is limited to test specimens subjected to constant amplitude uniaxial loading, where the machine is controlled such that the test specimen is subjected to repeated cycles of constant amplitude force (strain). Shear stress or applied force can be used as a constant amplitude fatigue variable.

Values ​​stated in SI units or inch-pound units will be considered standard separately. The values ​​specified in each system may not be exactly equivalent; therefore, each system should be used independently of the other.

This standard does not purport to address all, if any, safety concerns associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory restrictions prior to use.
