延性损伤 [
yán xìng sǔn shāng]
[力] ductile damage
- 介绍了金属延性动态损伤的微孔生长模型的研究方法和一般内容。
The studying method and the general contents of microvoids growth models for dynamic ductile damage of metals are introduced and the newest models are evaluated. - 该方法不仅考虑了疲劳诱导的累积塑性损伤,同时考虑了循环蠕变和静蠕变诱导的延性耗竭损伤。
The model not only considers the cumulated plastic damage induced by fatigue, but also considers the ductility exhaustion damage caused by cyclic and static creep. - 本文系统地回顾了高加载率下金属材料延性损伤的细观研究现状,对现有的各种动态延性损伤模型进行了评述。
In This paper the status and develepment in research of dynamic ductile damage of metals are reviewed, and the popular mesoscopic models in this field are also discussed.
