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. 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.

ASTM E Conducting Force Controlled Constant Amplitude Axial Fatigue Tests_百度文库

For cylindrical specimens, alignment should be checked by means of a trial test specimen with longitudinal strain gages placed at four equidistant locations around the minimum diameter. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?

Continue the test until astm e specimen failure criterion is reached or until a predetermined number of cycles has been applied to the specimen. View online Borrow Buy. Link to Active This link will always route to the current Active version of the standard.

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. In the typical regime of 10? Open to the public ; The following documents, although not directly referenced in the text, are considered important enough to be listed in this practice For specimens that are less than 0.

Regardless of the machining, grinding, or polishing method used, the? Touchstone is experienced in the astm e of fatigue testing in almost every astm e system and at a wide variety of temperatures from cryogenic to over? The test forces should be monitored continuously in the early stage of the test and periodically, thereafter, to ensure that the desired force cycle is maintained.

The following documents, although not directly astm e in the text, are considered important enough to be listed in this practice: This single location in All: Already Subscribed to this document. The results may also be used as a guide for the selection of metallic materials for service under conditions of repeated direct stress.

Obvious abnormalities, such as cracks, machining marks, gouges, undercuts, and so forth, are not acceptable.

Since specimen preparation can strongly in? 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.

The results may also be used as a astm e for the selection of metallic materials for service under conditions of repeated direct stress. The value of 1. E — 07 fatigue test the permanent deformation of the unbroken but tested specimens for example, percent change in cross-section area of test section should be reported.

The reduced section length should be greater than three times the minimum test section diameter.
