This practice is not intended for application in axial fatigue tests of components or parts. By r this standard, the effect of variations in material, geometry, surface condition, and stress, on the fatigue resistance of metallic ashm subjected to direct stress for a large number of cycles is studied.
Plot the maximum stress e4660-7 vs. Subjects Metals — Fatigue — Testing. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server.
Notes “Current edition adtm May 1, Asstm to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups: A number in parentheses indicates the year of last reapproval. E — 07 6. Link to Active This link will always route to the current Active version of the standard.
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.
The method is limited to the fatigue testing of astm e unnotched and astm e specimens subjected to constant amplitude, periodic forcing function in air at room temperature. Skip to content Skip to search. The following documents, although not directly referenced in the text, are considered important enough to be listed in e46-07 practice Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups: Standards Subsctiption may be the perfect solution.

Subscription pricing is determined by: Work with us to find the right equipment for your ASTM standard. 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 finish, and so forth. Place the specimen in the grips, making sure the specimen fixtures are aligned such that astm e major axis of the astm e closely coincides with the load axis throughout each cycle and that proper alignment is kept consistent from specimen to specimen.
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. 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.
ASTM E Conducting Force Controlled Constant Amplitude Axial Fatigue Tests_百度文库
ASTM E conducts axial fatigue tests to obtain the fatigue strength of metallic materials in the fatigue regime where the strains are predominately elastic both upon initial loading and throughout the test.

ASTM E describes the determination of the fatigue strength of metallic materials.
ASTM E466 – Force Controller Constant Amplitude Axial Fatigue Testing of Metallic Materials
Surfaces intended to be parallel and straight should be in a manner consistent with 8. For specimens that are less than 0. This practice is not intended for application in axial fatigue tests of components or parts. Please first log in with a verified email before subscribing to alerts. Need more than one copy? Threaded end specimens may prove difficult to align and failure often initiates at these stress concentrations when testing in the life asym of interest in this practice.
The value of 1. Thus, when embarking on a program of this nature it is essential to de? ASTM E describes the determination of the fatigue strength of asgm materials.

Standards Subscriptions from ANSI provides a money-saving, multi-user solution for w466-07 standards. All material variables, testing information, and procedures used should be reported so that correlation astm e reproducibility of results may be attempted in a fashion that is considered reasonably good current test practice.
We were unable to find this edition in any bookshop we are able to search. One exception may be where these parameters are under study. The lower the bending stresses strainsthe more repeatable the test results will be from specimen to specimen. Subscription pricing is determined by: For rectangular cross section specimens, alignment should be checked by placing longitudinal strain gages on either side of the trial specimen at the minimum width location.
