But it is difficult to research the loading rate dependency of complete stress-strain curve for rock. Recently a method was proposed, in which the loading rates were alternated between slow and fast rates at a uniform strain interval. This method is so simple that special equipment or technique isn't required. With the aid of this method, two stress-strain curves corresponding to two loading rates can be estimated from just one specimen. In this study, the alternating loading rate test was applied to compression and tension tests for not only Class I rock but also Class II rock, which has a positively inclined portion of the stress-strain curve in the post-failure region. Loading rate dependency of complete stress-strain curves of Class I and Class II rocks were examined. Experimental results indicate that this testing method can be adopted to research the loading rate dependency of complete stress-strain curve of Class I and Class II rocks under various stress state.
