These tests are conducted to examine and evaluate the behavior, susceptibility, and extent of resistance of certain materials to sharp-notch tension, tear, axial fatigue, strain-controlled fatigue, surface crack tension, creep crack, and residual strain.

Otherwise, the sections may be either of two types: Consumer Product Evaluation Standards. This practice is not intended for application in axial fatigue tests of components or parts.
It is advisable to determine these astk residual stresses with X-ray diffraction peak shift or similar techniques, and that the value of the surface residual stress be reported along with the direction of determination that is, longitudinal, transverse, radial, and so forth. Since specimen preparation can strongly in?
astk For example, specimen alignment is of utmost importance and FIG. Your comments are invited either for revision of this standard or for additional standards and should be addressed asfm ASTM International Headquarters.
One set of strain gages should be placed at the center of the gage length to detect misalignment that causes relative rotation of the specimen ends about axes perpendicular to the specimen axis. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
The trial specimen should be rotated about its longitudinal axis, installed and checked in both orientations within the?
Redline Version Ee2 Ee1 E NOTE 1—The following documents, although not directly referenced in the text, are considered important enough to be listed in this practice: The acceptable ratio of the areas test section to grip section to ensure a test section failure is dependent on e466–96 specimen gripping method. The area restrictions should be the same as for the specimen described in 5.
Redline Version Ee1 E However, regardless of the nature of the forcing function, it should be reported sine, ramp, saw tooth, etc. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.

Ea Ea Ee1 E Thus, when embarking on a program of this nature it is essential to define and maintain consistency a priori, as many variables as reasonably possible, with as much economy as prudent. This practice is limited to the fatigue testing of axial unnotched and notched specimens subjected to a constant amplitude, periodic forcing function in air at room temperature.
Fatigue Standards and Fracture Standards
Durability of Nonmetallic Material Standards. E – 05 e1 See all versions E e1 E E This practice is not intended for application in axial fatigue tests of components or parts. As a conservative general measure, this procedure is recommended unless: E – 15 See all versions Redline Version E For tests run in compression, the length of the test section should be approximately two times the test section diameter to minimize buckling.
Failure may be de? Fire Standards and Flammability Standards.

In view of this, no maximum ratio of area atm to test section should apply. Fillet undercutting can be readily determined by inspection. Fatigue Standards and Fracture Standards ASTM’s fatigue and fracture axtm provide the appropriate procedures for carrying out fatigue, fracture, and other related tests on specified materials.
