Standard Test Method for Determination of Resistance to Stable Crack Extension under Low-Constraint Conditions
|Publication Date:||15 June 2006|
|ICS Code (Mechanical testing of metals):||77.040.10|
1.1 This standard covers the determination of the resistance to stable crack extension in metallic materials in terms of the critical crack-tip-opening angle (CTOAc), c and/or the crack-opening displacement (COD), 5 resistance curve (). This method applies specifically to fatigue pre-cracked specimens that exhibit low constraint (crack-length-to-thi
1.2 Materials that are evaluated by this standard are not limited by strength, thickness, or toughness, if the crack-length-to-thic
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses (English) are for information purposes only.
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 and health practices and determine the applicability of regulatory limitations prior to use.
