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|
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), Ψc and/or the crack-opening displacement (COD), δ5 resistance curve (1).2 This method applies specifically to fatigue pre-cracked specimens that exhibit low constraint (crack-length-to-thi
Materials that are evaluated by this standard are not limited by strength, thickness, or toughness, if the crack-length-to-thic
