摘要
采用斜裂纹矩形梁四点弯曲试件对低合金转子钢在(Ⅰ+Ⅲ)复合型加载条件下裂纹的起始扩展特点、疲劳门槛限以及裂纹扩展行为作了研究,对所得到的规律进行了分析和讨论,并与(Ⅰ+Ⅱ)复合型疲劳裂纹扩展特点作了比较。
(Ⅰ+Ⅲ)combined mode fatigue thresholds and crack growth behaviour of rotor steels were stud- ied by using four-point bending specimens with inclined slots.The results were discussed, analysed and compared with(Ⅰ+Ⅱ)combined mode crack growth.
