This practice is not intended for application in axial fatigue tests of components or parts. If you need to be able to add standards to the monitoring service, you must register as a user with your own username ast password. 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.

Thus, when embarking on a program of this nature it is essential to define and maintain consistency a f466-07, as many variables as reasonably possible, with as much economy as prudent. Touchstone is experienced in fatigue specimen preparation to comply with strict asttm preparation requirements, including surface finish of the machined sample.

ASTM E466 Fatigue Testing
The results may also be used as a guide for the selection of metallic materials for service under conditions of repeated asfm stress. Subscription – always available and updated A web subscription provides an easy and secure access to standards, and you are guaranteed to always have the latest edition. Touchstone is experienced in the performance of fatigue testing in almost f466-07 material system and at a wide variety of temperatures from cryogenic to over ? This service is not available if you are a URL user where you do not log in with an email address.
All material variables, testing information, and procedures used should be reported so that correlation and reproducibility of results may be attempted in a fashion that is considered reasonably good current test practice. This ensures that you are always up-to-date and saves you both time and money. By following this standard, the effect of variations in material, geometry, surface condition, and stress, on the fatigue resistance of metallic materials subjected to direct stress for a large number of cycles is studied.

Touchstone Research Laboratory, Ltd. ASTM E conducts axial fatigue tests to obtain the fatigue strength of metallic materials in the fatigue regime where astj strains are predominately elastic both upon initial loading and throughout the test. Link to Active This link will always route to the current Active version of the standard.
The following documents, although not directly referenced in the text, are considered important enough to be listed in this practice: The results are suitable for application to design only when the specimen test conditions realistically simulate service conditions. Place the specimen in the grips, making sure the specimen fixtures are aligned such that the major axis of the specimen closely coincides with the load axis throughout each cycle and that proper alignment is kept consistent from specimen to specimen.
The moment new editions of the standards you monitor are released, changes are made, or appendixes are published, you will be alerted by email. Machining methods and techniques can strongly influence the fatigue life of a material. The test may also be used as a guide to the selection of metallic materials for service under conditions of repeated direct stress.
The method is limited to the fatigue testing of axial unnotched and notched specimens subjected to constant amplitude, periodic forcing function in air at room temperature. You need to log in before adding standards to the monitoring service. A web subscription provides an easy and secure access to standards, and you are guaranteed to always have the latest edition. 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.
Webprint Printed and bound. Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups:. Proper machining techniques prevent the introduction of stress risers or crack initiation sites. Historical Version s – view previous versions of standard. Continue the test until the specimen failure criterion is reached or until a predetermined number of cycles has been applied to the specimen. Start the axial force fatigue testing.
The condition of the test specimen and the method of test specimen preparation are critical to this procedure.

Standards monitoring is a free service designed for you who wish to be alerted of changes to or new editions of the standards required in your work.
Awtm test method is applicable for axial unnotched and zstm specimens subjected to constant amplitude, periodic force. ASTM E describes the determination of the fatigue strength of metallic materials in the fatigue regime where the strains are predominately elastic, both upon initial loading and throughout the test.
The lower the bending stresses or the strains, the more repeatable test results will be from specimen to specimen.
Strain gauges may be placed on the gauge length following ASTM E to determine the bending stresses or the strains on the specimen. Read more about subscriptions. Techstreet standards in subscription. The benefits of a subscription: This knowledge and care provides the most meaningful and best possible high cycle fatigue life results.
The ASTM E axial load fatigue test is used to determine the effect of variations in material, geometry, surface condition, stress, etc. Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups: Select from list below: Plot the maximum stress level vs. We are happy to help!
