Since a hydrostatic tension or compression hardly influences the relation between the maximum shear stress and the principle strains, the axial and the radial stress-strain relations for uniform straining under bi- and triaxial loading can be derived from this formula. It is shown how the uniform...

The prediction formula of time to failure was established for hard rock, considering the effect of σ2. The test results show that the time to failure of rock samples increases with the decrease of the stress-strength ratio (SSR = (σ1-σ3)/(σp-σ3)) under the same σ2 and σ3 ...
The sensitivity of oil reservoir rocks to stress is the basis for oilfield development, which determines the production method employed in the field. Therefore, it is critical to understand the stres...
Considering the swelling stress and gas pressure, we intensively studied the effective stress formula of coal containing gas. Then, the effective stress was taken into consideration in the nonlinear Nishihara creep model. Furthermore, the tertiary creep factor n was introduced in the nonlinear model ...

According to formula (1), the fitting results are shown in Figure 4. Figure 4 Open in figure viewerPowerPoint Relationship between confining pressures and peak stress. It can be seen from Figure 4 that the correlation coefficient R2 of the triaxial compression test results fitted is 0.999, ...
The monitoring system mainly collects stress, strain and AE data. Considering that the bearing bodies of underground structures are directly stressed, the axial force control loading method is adopted this time. Referring to the relevant literature and the mechanical properties of the experimental ...
The structure can be used in any suitable sensing arrangement. Two illustrative but not limiting possibilities are a triaxial sensor and a uniaxial sensor. In either sensor, the central block proof mass, reacting to an acceleration, applies a stress to the piezoelectric layer, resulting in a pote...
