摘    要：本文阐述了断裂力学发展的一般情况,将其发展分成三个时期:(1)初始期;(2)创建期;(3)发展期。对国内外金属断裂宏观研究中的理论研究、实验技术与工程应用的现状作了综述。对其今后发展趋向也作了预测。强调指出综合研究的重要性。

Abstract: In this paper general situation of the development for fracture mechanicsfirstly described and divided into three periods:(1)initial period,(2)crea-ted period(3)period of the development.Furthermore,it is reviewed thatpresent situation for theoretical investgation,the laboratorial technique andengineering application of the metallic material fracture macroinvestigate athome and abroad.At Last the trends in future development of fracture mecha-nics is also expected.It is emphasized the importance of the associative inve-stigation.
