V-Notched Shear ASTM D
The materials are either continuous-fiber or discontinuous-fiber-reinforced composites. Referenced Documents purchase astmm The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Strain gages can be applied to both sides of the specimen to assure that shear and not twisting occurs and failure must occur by shear.
Historical Version s – view previous versions of standard.
Need help or have a question? To conduct this test a rectangular flat strip composite material coupon is symmetrically v-notched. ASTM D testing determines the shear properties of composite materials that are reinforced by high-modulus ast. The test specimens are 76 x 11 mm at composite thickness with a V notch above and below the 11mm dimension. Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Properties, in the test direction, which may be obtained from this test method, include the following:.
Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the s5379 groups:. Note 1 — This shear test concept was originally developed without reference to fiber direction for asmt on isotropic materials such as metals or ceramics.
