2) crack initiation
裂纹萌生
1.
Simulating the drill string s crack initiation and propagation which is based on ABAQUS;
基于ABAQUS模拟钻柱裂纹萌生和扩展
2.

研究了压力容器用钢16MnR在低周疲劳下微孔(40~200μm)的裂纹萌生与扩展规律。
3.
The results show that the fatigue crack initiation is frequently associated with the slip bands and the carbides at the specimen surfaces.
研究了K40S钴基高温合金在700℃和900℃温度条件下由应变控制的高温低周疲劳行为,对疲劳断口形貌进行观察,结果表明:在高温低周疲劳加载条件下,K40S合金疲劳裂纹萌生机制为表面滑移带开裂与表面碳化物相界面开裂的综合作用;疲劳裂纹萌生与扩展方式为穿晶型,瞬断区呈现枝晶断裂特征;碳化物可作为障碍,阻碍疲劳裂纹的扩展,且为主要的二次裂纹策源地;K40S合金高温低周疲劳断裂为机械疲劳与高温环境氧化共同作用的结果。
3) crack initiation energy
裂纹萌生功
1.

研究了加入一定量成核剂的聚丙烯材料的冲击断裂行为 ,通过在一般Charpy冲击实验中采用仪表示波系统测定了材料的载荷 -时间曲线 ,通过该曲线将冲击断裂过程分为裂纹萌生和裂纹扩展两阶段 ,并计算出了裂纹萌生功和裂纹扩展功。
5) crack initiation region
裂纹萌生区
1.
The fracture surface was divided into crack initiation region and crack propagation region.
PA6/SGF的缺口拉伸断面主要分为裂纹萌生区及裂纹扩展区,基体的塑性变形主要集中在裂纹萌生区,剧烈的塑性变形可使基体上出现明显的孔洞。
6) crack initiation and propagation
