The rationality of logarithmof effective critical extension force as a linear function of the fractal dimensionali-ty of the fracture was analyzed in theory. The explanation in approach to studyingmaterial toughness using the fractal has been clarified. Key words:  defect gauge field      fractal dimensionality      critical extension force      Received:  18 February 1990      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/Y1990/V26/I2/69 1 Lung C W (龙期威).
