摘要
根据国内外断裂力学性能的研究文献,对止裂韧性的研究现状进行了概括总结。综述了钢中裂纹止裂的能量原理,介绍了止裂韧性测试方法和止裂在实际中的应用。
The research status of crack arrest toughness was summarized,based on the papers about fracture properties at home and abroad. The energy principle of crack arrest and methods of measuring are described. The applications of crack arrest in practice are illustrated at last.
