Description

ASTM E647-23b

Historical Standard: Standard Test Method for Measurement of Fatigue Crack Growth Rates

ASTM E647

Scope

1.1 This test method2 covers the determination of fatigue crack growth rates from near-threshold (see region I in Fig. 1) to K_max controlled instability (see region III in Fig. 1.) Results are expressed in terms of the crack-tip stress-intensity factor range (ΔK), defined by the theory of linear elasticity.

1.9 Special requirements for the various specimen configurations appear in the following order:

1.10 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.11 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
