Key words:  fractal dimension      fracture      critical crack extension force      Received:  18 June 1994      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1994/V30/I6/269 1MandelbrotBB,PassjaDE,PaullayAJ．Nature,1984;308:721．2苏辉,张玉贵,阎振．金属学报,1989;25:A466．3苏辉,张玉贵,阎振．钢铁研究学报,1991;3:69．4RayKK,MandelG．ActaMetall,1992;40:463．5PandeCS,RichardsLE,LiuatN,CempseyBD,SchwoebleAJ．ActaMetall,1987;35:1633．6LungCW(龙期威)．In:PietroneroLeds．,FractalsinPhysics,1986;189．7MuZQ(穆在勤),LungCW(龙期威)．JPhysRevB,1988;21:848．8LungCW(龙期威),MuZQ(穆在勤)．PhysRevB,1988;38:11781．9董连科．分形理论及其应用,沈阳:辽宁科学技术出版社,1991:187．10．董连科．王晓伟．金属学报,1990;26:A145．11．徐振兴,断裂力学,长沙:湖南大学出版社．1987:48,52,104,212．12．屈世显．董连科．高压物理学报,1993;7:127．N [1] YANG Du, BAI Qin, HU Yue, ZHANG Yong, LI Zhijun, JIANG Li, XIA Shuang, ZHOU Bangxin.
