Touchstone Research Laboratory, Ltd. Link to Active This link will always route to the current Active version of the standard.
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. 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.
This avoids complications that prevent the true strength of the material from being evaluated. 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.
ASTM E466 Load Controlled Constant Amplitude Fatigue Tests of Metals
ASTM E 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. This test method is applicable for axial ashm and notched specimens subjected to constant amplitude, periodic force.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Have a question about conducting the test for this standard? 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.
This knowledge and care provides the most meaningful and best possible high cycle fatigue life results. Place the specimen securely in the grips of the testing machine. We are happy to help! Continue sinusoidal cycles to failure.
ASTM E466 Metallic Materials Fatigue Testing
By means of our fatigue testing expertise and modular product design, we will help find the solution that is right for you. Take care to properly align the zstm. Start the axial force fatigue testing.
The results are suitable for application to design only when the specimen test conditions realistically simulate service conditions. Static and fatigue forces up to 25 kN 5, lbf Frequency ratings up to Hz Servohydraulic Small, portable footprint.
The results may also be used as a guide for the selection of metallic materials for service under conditions of repeated direct stress. Testing Procedure Place the specimen securely in the grips of the testing machine.
ASTM E Metallic Materials Fatigue Testing – ADMET
Touchstone is experienced astk fatigue specimen preparation to comply with strict sample preparation requirements, including surface finish of the machined sample. The lower the bending stresses or the strains, the more repeatable test results will be from specimen to specimen.
Plot the maximum stress level vs. Specimens can be round or flat.
The test may also be used as a guide to the selection of metallic materials for service under conditions of repeated direct stress. Sales Support Calibration Calculators. 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 ? Work with us to find the right equipment for ast, ASTM standard. We are confident that we have what you are looking for.
ASTM E Load Controlled Constant Amplitude Fatigue Tests of Metals
Due to the very large number of tests offered, descriptions of those most commonly requested have been gathered into the following groups: Strain gauges may be placed on the gauge length following ASTM E to determine the bending stresses or the strains on the specimen. Take care to adjust the specimen symmetrically to distribute the load uniformly over the cross section.
