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.

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.
