E – 10 See all versions E Ee1 E Redline Version Ee1 E E Your comments will receive careful consideration at a meeting of the responsible technical committee, which you aztm attend. Ee1 E E E The size of the gripped end relative to the gage section, and the blend radius from gage section into the grip section, may cause premature failure particularly if fretting occurs in the grip section or if the radius is too small.

This practice is not intended for application in axial fatigue tests of components or parts. For specimens having a uniform gage length, it is advisable to place a similar set of gages at two or three axial positions within the gage section. E — 07 with as much economy as prudent. 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.

In the typical regime of 10? E e1 E E Threaded end specimens may prove awtm to align and failure often initiates at these stress concentrations when testing in the life regime of interest in this practice.
Last previous edition approved in as E — 96 ? E — 07 FIG.
To do so would require the control or balance of what are often deemed nuisance variables; for example, hardness, cleanliness, grain size, composition, directionality, surface residual stress, surface?

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.
This practice is not intended for application in axial fatigue tests of components or parts. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.
NOTE 2—Measurements of dimensions presume smooth surface? The following documents, although not directly referenced in the text, are considered important enough to be listed in this practice: It is important that the accuracy of alignment be kept consistent from specimen to specimen. E – 02 e1 See all versions E e1 E E Every effort should be made to prevent the occurrence of misalignment, either due to twist rotation of the gripsor to a displacement in their axes of symmetry.
ASTM’s fatigue and fracture standards provide the appropriate procedures for carrying out fatigue, fracture, and other related tests on specified materials. Because of this, a circular cross section may be preferred if material form lends itself to this con?
Otherwise, the sections may be either of two types: ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.

E — 07 6. These fatigue and fracture standards are useful to manufacturers and other users concerned with such materials in understanding their failure and stability mechanisms.
The area restrictions should be the same as for the specimen described in 5. Redline Version Ee2 Ee1 E All material variables, testing information, and procedures used should be reported so that correlation and reproducibility axtm results may be attempted in a fashion that is considered reasonably good current test practice.
For example, specimen alignment is of utmost importance and FIG. For specimens that are less than 0. Unmanned Maritime Vehicle Standards. Since specimen preparation can strongly in? Rolling Element Bearing Standards. 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.
