标准范围

ISO 12108:2012描述了确定从疲劳裂纹扩展阈值应力强度因子范围到快速不稳定断裂开始的疲劳裂纹扩展速率的试验。ISO 12108:2012主要用于评估以线弹性应力为主的各向同性金属材料，且仅垂直于裂纹平面施加力（模式I应力条件），且应力比恒定。

ISO 12108:2012 describes tests for determining the fatigue crack growth rate from the fatigue crack growth threshold stress-intensity factor range to the onset of rapid, unstable fracture.ISO 12108:2012 is primarily intended for use in evaluating isotropic metallic materials under predominantly linear-elastic stress conditions and with force applied only perpendicular to the crack plane (mode I stress condition), and with a constant stress ratio.
