ASTM D5379 PDF

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.

Touchstone Research Laboratory, Ltd. A notched beam specimen is placed in a shear fixture.

Shear of Composite Materials by the V-Notched Beam Method

Properties, in the test direction, which may be obtained from this test method, include the following:. Select from list below: A special fixture is used to hold the coupon and load is applied at a specified rate until failure occurs. Inspection Validating the specifications, value and safety of your raw materials, products and assets. Standards can be obtained from appropriate standards authorities.

Properties determined from this test may be used for material specifications, research and development, quality assurance and structural design and analysis.

ASTM D testing determines the shear properties of composite materials that are reinforced by high-modulus fibers. Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups:.

A load is applied at a specified rate until specimen failure occurs. To conduct this test a rectangular flat strip r5379 material coupon is symmetrically v-notched.

Either in-plane or interlaminar shear properties may be evaluated, depending upon the orientation of the material coordinate system relative to the loading axis. Link to Active This link will always route to the current Active version of the aztm. Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups: 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.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. The sample preparation, including notching, can be done at your facility or by Touchstone. Note 1 — This shear test concept was originally developed without reference to fiber direction for use on isotropic materials such as metals or ceramics.

Need help or have a question? The test specimens are 76 x 11 mm at composite thickness with a V notch above and below the 11mm dimension. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Only a single shear plane may be evaluated for any given specimen. The materials are either continuous-fiber or discontinuous-fiber-reinforced composites.

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.

The test determines shear strain, shear stress and shear modulus. Combining values from the two systems may result in non-conformance with the standard.

The composite materials are limited to continuous-fiber or discontinuous-fiber-reinforced composites in the following material forms: Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. The data can be used for research and development purposes concerning interply strength or composite material comparison.

V-Notched Shear ASTM D5379

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. The composite materials are limited to continuous-fiber or discontinuous-fiber-reinforced composites in the following material forms:.

Through our network of over 43, people in 1, laboratories and offices in countries, Intertek provides quality and safety solutions to a wide range of industries around the world. Factors that influence the shear response and should therefore be reported include the following:
