查询词典 anomalous propagation

The fatigue propagation of surface cracks on overlay of hydrogenation reactor is seriously imperiling the safe run of hydrogenation reactor. It is attracted attention of engineering fields that a surface crack on overlay is able to either stop at the interface of overlay and base material or growth to base material under fatigue load.

本文从混凝土细观机理出发，采用翼型裂纹模型分析了围压荷载下混凝土内微裂纹扩展、弯折和相互作用直至材料破坏的过程。

Even though at a very low temperature (-196℃), the cleavage cracking dominates the fracture process, it can not propagate straight forward through entire ligament and shows the pop-in extension in macroscopic tests and the quasi-cleavage mode in microscopic feature. It is found that the strong resistance which hinders the crack propagation is provided by three barriers: original austenite grain boundaries, bainite colony boundaries and inter-layers between bainite laths.
