The fractograph exhibited typical ductile dimple fracture pattern. 断裂形式呈韧性断裂,断口以韧窝为主。
The fractured tubing was analyzed by fractographic inspection,metallographic examination,and mechanic property testing. 对油管进行了断口分析、金相检验、材料力学性能试验。
The fractographic features are small voids when PVC fracture mechanism is secondary fracture modle. 其断裂机制为次级裂纹破裂模式时形成微坑形貌;
And also the application of image processing technique on the fractographic quantitative analysis is interpreted. 阐 述了图象处理技术在断口定量分析上的应用。
The steel trea-ted with this pruccss shows a fractograph with quasi-cleavage and dimple. 钢的断口为准解理十韧窝属于韧性断裂。
Fractographic and metallographic examination, mechanical testing have been carried out on the failure analysis of the drilling collar. 对钻铤断裂原因进行了断口分析、金相检验和力学性能试验。
