目前,我国在断裂力学的研究应用方面,开展了很多工作。许多焊接结构中也开始用断裂力学方法来评价材料和结构的安全性,把断裂力学分析方法与产品设计、金属材料的研究和应用以及无损探伤等方面的工作结合起来,具有重要的现实意义。为适应现代工业技术的发展,根据广大读者的要求,本刊自本期起开辟《断裂力学》专栏,供大家学习参考。
At present, our country has carried out a lot of work in the research and application of fracture mechanics. Fracture mechanics is also used in many welded structures to evaluate the safety of materials and structures. It is of great practical significance to combine fracture mechanics analysis with product design, research and application of metal materials, and non-destructive testing. In order to meet the development of modern industrial technology, according to the requirements of readers, this issue from this issue to open up a “fracture mechanics” column for everyone to learn for reference.
