| Abstract: | By RFPA 2D (Rock Failure Process Analysis) Code,the failure processes of lots of rock specimens are simulated under uniaxial test.The influence of residual strength on elasticity,brittleness and plasticity of rock is mainly studied.The results of numerical simulation show that the residual strength has great effect on elasticity,brittleness and plasticity of rock,with the increase of residual strength,rock specimens perform more plasticity and higher peak compression strength. |

| Keywords: | rock residual strength elasticity brittleness plasticity numerical simulation |
