ASTM E606 Strain-Controlled High and Low Cycle Fatigue Testing

0 0

ASTM E606 covers testing procedures to measure the fatigue properties of nominally homogeneous materials by subjection to uniaxial forces. ASTM E606 is intended as a guide for fatigue testing performed at low and high cycles. Results can support such activities as materials research and development, mechanical design, process and quality control, product performance, and failure analysis. While this practice is intended primarily for strain controlled fatigue testing, some sections may provide useful information for force-controlled or stress-controlled testing.

ASTM E606

This standard works great for testing under various temperatures and strain rates. No restrictions are placed on environmental factors such as pressure, temperature, medium, humidity and others, provided they are controlled throughout the test, do not cause loss of or change in dimension with time, and are explained in the final report.

When testing for strain-controlled fatigue, it can be noted that it is influenced by the same variables that influence force-controlled fatigue. Strain-controlled fatigue testing has distinctive requirements on testing methods. In particular, cyclic total strain should be measured and cyclic plastic strain should be determined. Also, both strains are typically used to establish cyclic limits and total strain usually is controlled throughout the cycle.

A hydraulic fatigue test machine may be a good choice for ASTM E606 for versatile load rates. Consider taking a look at our wide variety of grips, extensometers and furnaces as well.
