AbolishedMetallic materials - Method of test for the determination of resistance to stable crack extension using specimens of low constraint
金属材料 低拘束试样测定稳定裂纹扩展阻力的试验方法
Application Summary AI generated
This standard specifies a test method for measuring the resistance of metallic materials to stable crack extension using specimens with low constraint, such as those with shallow cracks or under tension loading. It is applied in fracture mechanics testing to evaluate material toughness in scenarios where standard high-constraint specimens (like deep-cracked bend bars) would overestimate fracture resistance. The method is used primarily in materials research, quality control, and structural integrity assessments for industries like aerospace, pressure vessels, and pipelines.
