ASTM D is a testing standard designed to measure the shear properties of composite materials. Beam Method, or more commonly known as the Iosipescu Shear Method, was standardized into ASTM D in , while the V-Notched Rail Shear Method . ASTM D TESTING FIXTURE. SHEAR PROPERTIES OF COMPOSITE MATERIALS BY THE V-NOTCHED BEAM METHOD. 1. ASTM D Testing Fixture.

The test specimens are 76 x 11 mm at composite thickness with a V notch above and below the 11mm dimension. Certification Formally confirming that your products and services meet all trusted external and internal standards.
Only a single shear plane may be evaluated for any given specimen.
Properties determined from this test may be used for material specifications, research and development, quality assurance and structural design and analysis.
Historical Version s asstm view previous versions of standard. Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. The sample preparation, including notching, can be done at your facility or by Touchstone.
Assurance Testing Inspection Certification. Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups:.
Properties, in the test direction, which may be obtained from this test method, include the following: Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
Touchstone Research Laboratory, Ltd.
The composite materials are limited to continuous-fiber or discontinuous-fiber-reinforced composites in the following material forms: 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. The composite materials are limited to continuous-fiber or discontinuous-fiber-reinforced aatm in the following material forms:.

V-Notched Shear ASTM D5379
To conduct this test a rectangular flat strip composite material coupon is symmetrically v-notched. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
Standards can be obtained from appropriate standards authorities. Either in-plane or interlaminar shear properties may be evaluated, depending upon the orientation of the material coordinate system relative to the loading axis. Work Item s – proposed revisions of this standard. 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.
