If the failure is defined as the final fracture of a component, then both S-N curves and crack growth rate curves reflect the fundamental material behavior under fatigue loading.
如果都把一个构件的最终断裂作为疲劳破坏的定义，则S - N曲线和裂纹扩展率曲线均是反映金属在疲劳载荷作用下的基本材料特性。
High temperature fatigue creep test of 316l stainless steel under 1-step and 2-step load was conducted, the influence of the load history on material behavior was investigated emphatically.
