Analysis on Chaotic Behavior in Rock Damage Rheological Process under Uniaxial Stress

Abstract:

The evolutional laws of rock under uniaxial stress are studied based on damage mechanics, rock rheology mechanics and chaos theory. Firstly, the damage rheological evolution equations are set up on the base of damage mechanics under the isotropic and orthogonal anisotropy conditions. The chaotic characters are tested in the process of evolution and the chaotic effect is analyzed. The root reason of rock damaged is made clear. The creep curve of Kelvin model considering damage is illustrated by FLAC3D, and the deformation process is explained by chaos theory. It will be help to understand the mechanics property of rheology of damaged rock and predict development phases. It is also much value in solving various practical problems of geotechnical engineering and acquainting other materials’ rheology evolution..
