ASTM WK35142

    New Test Method for In-Plane Shear Properties of Sandwich Panels Using Picture Frame Fixture

    (What is a Work Item?)

    Developed by Subcommittee: D30.09 | Committee D30 | Contact Staff Manager



    WK35142

    1. Scope

    1.1 This test method covers determination of in-plane shear loading response of flat sandwich constructions. Permissible core material forms include those with continuous bonding surfaces (such as balsa wood and foams) as well as those with discontinuous bonding surfaces (such as honeycomb). 1.2 The square test specimen is mechanically fastened to a pinned metal frame on each edge. The frame is loaded in axial tension which produces shear forces on the panel edges. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. 1.2.1 Within the text, the inch-pound units are shown in brackets. 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.

    Versions of this test method are used in aerospace industry for design property development and quality control.
