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. For tests run xstm compression, the length of the test section should be approximately two times the test section diameter to minimize buckling.

Fatigue Standards and Fracture Standards

Sports Standards and Recreation Standards. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? For most conventional grips, good alignment must come about from very careful attention to design detail.

R466-96 following documents, although not e4669-6 referenced in the text, are considered important enough to be listed in this practice: 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.

To ensure test section failure, the grip cross-sectional area should be at least 1. E – 02 e1 See all versions E e1 E E E — 07 6.

In view of this fact, the method of preparation should be agreed upon prior to the beginning of the test program by both the originator and the user of the fatigue data to be generated.

These fatigue and fracture standards are useful to manufacturers and other users concerned with such materials in understanding their failure and stability mechanisms.

One exception may be where these parameters are under study. In view of this, no maximum ratio of area grip to test section should apply.

This practice is not intended for application in axial fatigue asfm of components or parts. This practice is not intended for application in axial fatigue tests of components or parts.

One set of strain gages should be placed at the center of the gage length to detect misalignment that causes relative rotation of the r466-96 ends about axes perpendicular to the specimen axis.

The value of 1. It is beyond the scope of Practice E to extrapolate beyond this range or to extend this assumption to other materials systems that may be viscoelastic or viscoplastic at ambient test temperatures and within the frequency regime mentioned.

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.
