1、Designation: B565 04 (Reapproved 2015)Standard Test Method forShear Testing of Aluminum and Aluminum-Alloy Rivets andCold-Heading Wire and Rods1This standard is issued under the fixed designation B565; the number immediately following the designation indicates the year oforiginal adoption or, in the
2、 case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope1.1 T
3、his test method covers the double shear testing ofaluminum and aluminum alloy rivets with round, solid shanksand cold-heading wire and rod.2NOTE 1Exceptions to this test method may be necessary in individualspecifications or methods for tests for a particular material.1.2 The values stated in inch-p
4、ound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use.

7、y Relating to Methods of Mechanical Testing3. Terminology3.1 GeneralThe definitions of terms relating to sheartesting in Terminology E6 are applicable to the terms used inthis test method.4. Summary of Test Method4.1 The test consists of subjecting a length of wire or rod ora rivet in full cross sec
8、tion, or a machined length of rod or rivet,to double-shear loading, with a suitable test device in a tensiontesting machine, and determining the shear stress required tofracture the specimen (that is, the shear strength).5. Significance and Use5.1 This test method is intended solely for the shear te
9、stingof rivets and cold-heading wire and rod, and is not generallyrecommended for the determination of the shear strength ofother products. For rivets, this method is limited to rivetshaving a shank length equal to or greater than 2d.NOTE 2The results of shear tests of specimens machined fromproduct
10、s other than wire, rod, and rivets may be greatly dependent uponthe orientation of the specimen within the original test material, and thedirection in which the force is applied relative to the grain flow in thespecimen.4It is recommended that shear strengths of other products bedetermined by Test M
11、ethod B769 for products greater than 0.250 in. (6.4mm) and Test Method B831 for products less than 0.250 in. (6.4 mm).Shear strengths developed by this test method have been shown to varyfrom those developed by other methods.4If Test Method B565 is used forshear testing of other products, variables
12、such as those described in TestMethod B769 should be identified and controlled.5.2 The results of shear tests are dependent upon the relativeand absolute lengths of specimen which are sheared out, andthose which are supported.4The results of tests made inaccordance with this method should not be dir
13、ectly comparedwith those determined in other types of tests in which themethods of loading and supporting the specimen are different.5.3 The presence of a lubricant on the surfaces of thespecimen and device may result in shear strengths up to 3 %lower than those determined in the absence of lubricat

17、8-2959. United States1NOTE 3In order to be able to test rivets having shanks as short as 2d,the supported lengths of the specimen are12 d (Fig. 1), although it isrecognized that higher values of shear strength would be obtained if thesupporting lengths were longer.5.4 Investigations have determined
18、that the shear strengthdecreases slightly as the clearance between the specimendiameter and the diameter of the test hole in the deviceincreases, and that the effect of the clearance decreases withincreasing specimen diameter. This test method (refer to Fig. 1)permits clearances for production testi
