Strategic Study of CAE 2007, Volume 9, Issue 11, Pages 11-15
In this paper, the principle of interaction between plastic volumetric Two new interactions of suction-plastic volumetric strain and pore air pressure-plastic volumetricstrain appear in the unsaturated state of a soil besides the interaction between plastic volumetricThereby the effect of the suction on plastic volumetric strain includes two opposite aspects.

Numerical simulation of the rockburst processes of a circular tunnel at different dilation angles
Wang Xuebin,Pan Yishan,Zhang Zhihui
Strategic Study of CAE 2010, Volume 12, Issue 2, Pages 40-46
Rockburst processes of a circular tunnel are modeled by use of FLAC at different dilation angles. To model the tunnel excavation, a FISH function is written and used to delete the elements in the tunnel. For rock elements exhibiting linear strain-softening behavior beyond the occurrence of failure and then ideal plastic behavior, the failure criterion is a composite Mohr-Coulomb criterion with tension cut-off. The present calculation is divided into three steps. Firstly, a hydrostatic pressure is applied to the plane strain model until a static equilibrium state is reached. Secondly, a tunnel is excavated using the written FISH function. Thirdly, the calculation renews to achieve a new equilibrium state. Results show that with an increase of the dilation angle, the shear band becomes wider; the dog-ear or V-shaped rockburst notch becomes deeper; the number of failed elements is greater and the plastic zone becomes bigger. At lower dilation angles, the apparent strain localization phenomenon is localized at V-shaped notches, the angle between a shear band and the tangential line of the tunnel surface is higher. However, at higher dilation angles, the angle is lower and the apparent strain localization phenomenon is localized at the tunnel surface. The present numerical results about the shear band inclination are consistent with the Roscoe and Arthur theories.
