Certain sandwich panel finite element programs require the Poisson’ratio of the honeycomb core. It is not possible to measure the honeycomb’Poisson’ratio by standard methods.

1. Scope

1.1 This test method covers the determination of the honeycomb Poisson's ratio from the anticlastic curvature radii, see .

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

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.
