Numerical simulation for anomalies of shear stress and failure process of rock under biaxial plane strain compression

WANG Xue-bin(Department of Mechanics and Engineering Sciences,Liaoning Technical University,Fuxin 123000,China)  
The anomalies of shear stress and failure process of a rock specimen under biaxial plane strain compression are modeled using Fast Lagrangian Analysis of Continua(FLAC).In the elastic stage,the adopted constitutive relation is linear elasticity.In the strain-softening stage,a composite Mohr-Coulomb criterion with tension cut-off is used and the post-peak constitutive relation is linear.The anomalies of shear stress in three periods with marked stress decrease beyond the peak stresses are analyzed.In the first and second periods,shear failure occurs on the specimen sides and in the gap,respectively,and earthquakes belong to the rupture type with apparent precursors.In the third period,new shear failure occurring outside the gap leads to rupture earthquakes;shear failure in the gap results in strike-slip earthquakes without precursor.In the process of failure,higher shear stress gradients appear in the shear fracture zone boundaries.Shear stress is lower at the zone center,reflecting the strain-softening behavior of rock in the zone.In the short-term stage,the migration is opposite.Though the anomalies of shear stress are especially complex prior to the strain-softening stages of the stress-strain curve,the shear stresses of different elements have similar or synchronous evolutionary regularities if the monitored elements are located at the same fracture zones.Precursors of shear stress on the condition of recurrence of earthquakes are possibly different due to different earthquake types.
