It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the aastm of regulatory limitations prior to use.

The test determines shear strain, shear stress and shear modulus.

V-Notched Shear ASTM D

The composite materials are limited to continuous-fiber or discontinuous-fiber-reinforced composites in the following material forms: Touchstone has extensive experience in utilizing different coupon geometries, the use of different tab materials and adhesives, and proper preparation of notches, all of which are critical to ensure accurate results. A notched beam specimen is placed in a shear fixture. Validating the specifications, value and safety of your raw materials, products and assets.

Note 1 — This shear test concept was originally developed without reference to fiber direction for use on isotropic materials such as metals or ceramics.

Shear of Composite Materials by the V-Notched Beam Method

To conduct this test a rectangular flat strip composite material coupon is symmetrically v-notched. The materials are either continuous-fiber or discontinuous-fiber-reinforced composites.
