This practice is not intended for application in axial fatigue tests of components or parts.
Record the load at the time of failure. 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. This practice is not intended for application in axial fatigue tests of components or parts.
Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups:. The lower the bending stresses or the strains, the more repeatable test astn will be from specimen to adtm. 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.
Strain gauges may be placed on the gauge length following ASTM E to determine the bending stresses or the strains on the specimen. We are confident that we have what you are looking for. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Plot the maximum stress level vs. Place the specimen securely in the grips of the testing machine. Specimens can be round or flat.
Testing Procedure Place the specimen securely in the grips of the testing machine. 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.
Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups: 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.
Link to Active This link will always route to the current Active version of the standard.
The test may also be used as a guide to the selection of metallic materials for service under conditions of repeated direct stress. Give our test engineers a call today for help configuring the best test machine and accessories according to ASTM E Select from list below: By means of our fatigue testing expertise and modular product asstm, we will help find the solution that is right for you.
Proper machining techniques prevent the introduction of stress risers or crack initiation sites. This test method is applicable for axial unnotched and notched specimens subjected to constant amplitude, periodic force.
This knowledge and care provides the most meaningful and best possible high cycle fatigue life results.
ASTM E466 Load Controlled Constant Amplitude Fatigue Tests of Metals
Continue sinusoidal cycles to failure. ASTM E is limited to the fatigue testing of axial ashm and notched specimens subjected to a constant amplitude, periodic forcing function in air at room temperature. Historical Version s – view previous versions of standard. Touchstone is experienced in fatigue specimen preparation to comply with strict sample preparation requirements, including surface finish of the machined sample.
ASTM E466 Metallic Materials Fatigue Testing
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. The results are suitable for application to design only when the specimen test conditions realistically simulate service conditions. Take care to properly align the specimen. 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.

ASTM E Metallic Materials Fatigue Testing – ADMET
Continue the test until the specimen failure criterion is reached or until a predetermined number of cycles has been applied to the specimen. 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 ast, and so forth.
We are happy to help! The condition of the test specimen and the method of test ast preparation are critical to this procedure.
ASTM E Fatigue Testing | Element
We e466 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.
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 ASTM E axial load fatigue test is used to determine the effect of variations in material, geometry, surface condition, stress, etc. Static and fatigue forces up to 25 kN 5, lbf Frequency ratings up to Hz Servohydraulic Small, portable footprint.
