Experimental results show that the logarithms of impact tough-ness increase monotonically with the increase of fractal dimension. The microstructures havea great influence on the fractal dimension. There is a certain correlation between the fractaldimension and fracture mechanism. Key words:  fractal dimension      impact toughness      measuring unit      fracture characteristic      Received:  18 June 1989      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/Y1989/V25/I6/82 1 Pande C S, Richards L E, Louat N, Cempsey B D, Schwoeble A J.
