High cycle fatigue test的意思|示意

Randomly distributed models of micro-plastic strains were used to calculate the micro-plastic deformation produced at each cycle of the steel under high cycle fatigue test.

采用金属材料微元屈服极限随机分布模型，计算出每次循环产生的微观塑性应变，并与用单调拉伸试验确定的材料真实断裂延性联系起来。

Ultrasonic fatigue tests were carried out on Q235B base metal and welded joints by an ultrasonic fatigue test equipment in order to investigate their super high cycle fatigue properties.

用超声疲劳试验装置对Q235B母材及焊接接头试件进行超声疲劳试验，研究其在超高周疲劳寿命区间的疲劳性能。

Based on the orthogonal test design, this paper studied the effect of low cycle stress, high-low cycle stress ratio , high cycle number and high cycle frequency on complex fatigue life.

在高低周复合疲劳研究中采用了正交试验设计的方法，并以此为基础综合研究了低周应力、高低周应力比、高周循环次数和高周循环频率对复合疲劳寿命的影响及其机理。
