本文件描述了用于确定从疲劳裂纹扩展阈值应力强度因子范围Δ Kth到快速、不稳定断裂开始的疲劳裂纹扩展速率的试验。本文件主要用于评估主要为线弹性应力条件下的各向同性金属材料，力仅垂直于裂纹平面施加（I型应力条件），力比为恒定。
This document describes tests for determining the fatigue crack growth rate from the fatigue crack growth threshold stress-intensity factor range, ΔKth, to the onset of rapid, unstable fracture.This document 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 force ratio, R.
