Thus, when embarking on a program of this nature it is essential to define and maintain consistency a priori, as aetm variables as reasonably possible, with as much economy as sstm.
Testing Procedure Place the specimen securely in the grips of the testing machine. Continue the test until the specimen failure criterion is reached or until a predetermined number of cycles has been applied to the specimen. Touchstone is experienced in fatigue specimen preparation to comply with strict sample preparation requirements, including surface finish of the machined sample.
Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups: 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. The method is limited to the fatigue testing of asttm unnotched and notched specimens subjected to constant amplitude, periodic forcing function in air at room temperature.
Sales Support Calibration Calculators. 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.
We are happy to help! 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. The following documents, although not directly referenced in the text, are considered important enough to be listed in this practice: Select from list below: Machining methods and techniques can strongly influence the fatigue life of a material.
ASTM E466 – Force Controller Constant Amplitude Axial Fatigue Testing of Metallic Materials
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. 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.
This test method is applicable for axial unnotched and notched specimens subjected to constant amplitude, periodic force. Touchstone Research Laboratory, Ltd. Continue sinusoidal cycles to failure. We are confident that we have what you are looking for. The results may also be used as a guide for the selection of metallic materials for service under conditions of repeated direct stress.
Start the axial force fatigue testing. Strain gauges may be placed on the gauge length following ASTM E to determine the bending stresses or the strains on the specimen. Place the specimen securely in the grips of the testing machine. The results are suitable for application to design only when the specimen test conditions realistically simulate service conditions.
Have a question about conducting the test for this standard? Record the load at the time of failure. Proper machining techniques prevent the introduction of stress risers or crack initiation sites. 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.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
ASTM E is aztm to the fatigue testing of axial unnotched and notched specimens subjected to a constant amplitude, periodic forcing function atsm air at room temperature. We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications.
Static and fatigue forces up to 50 kN 11, lbf Frequency ratings up to 75 Hz Oil-free, all electric actuator for clean test conditions Lower purchase, operating, and mantenance costs than hydraulic equivalents.
Work with us to find the right equipment for your ASTM standard. This knowledge and care provides the most meaningful and best possible high cycle fatigue life results. By means of astj fatigue testing expertise and modular product design, we will help find the solution that is right for you.
Take care to adjust the specimen symmetrically to distribute the load uniformly over the cross section.
Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups:. ASTM E covers axial force controlled fatigue tests of metallic materials in the fatigue regime where strains are predominately elastic, both at initial loading and throughout the test.

The test may also be used as a guide to the selection of metallic materials for service under conditions of repeated aatm stress. Specimens can be round or flat. This practice is not intended for application in axial fatigue tests of components or parts. Place the specimen in the grips, making sure the specimen fixtures are aligned such that the major aetm of the specimen closely coincides with the load axis throughout each cycle and that proper alignment is kept consistent from specimen to specimen.
The ASTM E axial load fatigue test is used to determine the effect of variations in material, geometry, surface condition, stress, etc. Touchstone is experienced in the performance of fatigue testing in almost every material system and at a wide variety of temperatures from cryogenic to over ? The lower the bending stresses or the strains, the more repeatable test results will be from specimen to specimen.
Static and fatigue forces up to 25 kN 5, lbf Frequency ratings up to Hz Servohydraulic Small, portable footprint. This avoids complications that prevent satm true strength of the material from being evaluated.
The condition of the test specimen and the method of test specimen preparation are critical to this procedure. Take care to properly align the specimen.
This practice is not intended for application in axial fatigue tests of components or parts.
