摘要
本文综述了钢中裂纹止裂的有关概念,重点介绍了裂纹止裂研究的发展、裂纹止裂理论、止裂韧性测试方法以及钢的止裂特性,指出了止裂课题研究的重点,最后举例说明了裂纹止裂在实际工程结构上的应用。
The paper describes the basic concept of crack arrest insteels. The history of development of crack arrest, theories of crack arrest, methods of measuring arrest toughness and crack arrest characteristics of steels are reviewed in details. The focal points of crack arrest study are pointed out. The applications of crack arrest in practice in engineering are illustrated at last.
