Usually the most critical stress to which a sandwich panel core is subjected is shear. The effect of repeated shear stresses on the core material can be very important.

These test methods provide a standard method of obtaining the sandwich core shear fatigue properties.

1. Scope

1.1 This test method covers determination of the effect of repeated shear loads on sandwich core materials.

1.2 The values stated in SI units are to be regarded as the standard. The inch-pound units given may be approximate.

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

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
