摘要 | This paper investigated the theoretical relationship between the axial strain thresholds at the volumetric strain reversal point (epsilon (1cd)) and the strain threshold at the peak stress (epsilon (1ucs)) during a uniaxial compression test. Firstly, we used renormalization group theory with the stress transfer mechanism to reveal the essence of the phase transition phenomenon at the axial strain threshold (epsilon (1cd)). Then, we constructed mathematical expressions for epsilon (1ucs) and epsilon (1cd), respectively. Finally, a theoretical expression for the normalized quantity epsilon (1ucs)/epsilon (1cd) was deduced. Results indicate that the theoretical solution of epsilon (1ucs)/epsilon (1cd) is a function of the shape parameter m. We determined m values in the granitic gneiss experiments presented in Part I of this paper, and then compared the experimental results with theoretical solutions for epsilon (1ucs)/epsilon (1cd). It was observed that, for a given m, the experimental results were approximately consistent with the theoretical values for the two- and three-dimensional renormalization group models. This indicates that the two- and three-dimensional renormalization group models of rock fracture processes can be used to describe the mechanical behavior of laboratory-scale rock samples. Therefore, this study has thrown some light on failure prediction for laboratory-scale rock samples. Furthermore, the results show that epsilon (1ucs)/epsilon (1cd) can be regarded as a potential indicator for predicting the failure strain of laboratory-scale rock samples. |
