Besides scientific investigations for fatigue and fracture mechanics, ultrasonicfatigue is also used for industrial applications.
超声疲劳不仅属于疲劳学和断裂力学的基础研究,而且其成果已应用于航空、航天等工业领域。

A modifying coefficient of load frequency is used to describe the effect of load frequency on fatigue behavior in ultrasonicfatigue testing.
采用一个超声加载频率修正系数对超声疲劳性能试验中载荷频率对疲劳性能的影响进行修正。
