The bonded loading plates are either pulled in tension or pushed in compression on a Satm Test Machine in order to shear the material within 3 to 6 minutes. This test method provides information on the force-deflection behavior of sandwich constructions or cores when loaded in shear parallel to the plane of the facings.
Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. It covers the determination of shear strength parallel to the plane of the sandwich, and the shear modulus associated with strains in a plane normal to the facings.
Inspection Validating the specifications, value and safety of your raw materials, products and assets. This test method is used to determine core shear properties of a sandwich construction material using loading plates bonded to the outer surfaces or skins facesheets.

Need help or have a question? The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Approximate shear properties can asmt be obtained from a sandwich flexure test see Test Method C The test may be conducted on core materials bonded directly to the loading plates or the sandwich facings bonded to the plates. Combining values from the two systems may result in non-conformance with aetm standard.
From a complete force-deflection curve, it is possible to compute core shear stress at any force such as the shear stress at proportional limit, at yield, or at maximum force and to compute an effective core shear modulus.
