EFFECTS OF SAMPLE SIZE, PRECRACKED LENGTH AND TEMPERATURE ON THE TOUGHNESS K_(IC) OF FRACTURE

Xu Zhaoyong Bao Yifeng Li Zhongfu Wang Haitao (Seismological Bureau of Yunnan Province)  
Using the Tali, Yunnan, heterogeneous marble as samples, K_(IC) is determined by three-points bending method. The results indicate that K_(IC) values are more scattered for heterogeneous marble samples. There is no obvious difference between both K_(IC) values determined by prenotched and precracked samples(They are 134.8±32.8 kg. cm~(-3/2) and 137.9±31.0 kg. cm~(-3/2), respectively). And when samples increase to an adequate size and thickness, K_(IC) values tend to be stable as 139.3±27.7 kg. cm~(-3/2). But temperature has great effect on K_(IC) values: whereas temperature increases from 25℃ to 400℃, it decreases about 30%. At the same time, it can be seen from results of the acoustic emission that features of the acoustic emission of fractures ar related to the loaded speed,
