Numerical Simulation on Tensile Fracture Process of Multi-Crack Rock Bridge

Abstract:

In order to study the tensile failure of rock bridge, the finite element software which can simulate the cracking of pull and tensile stress was used to simulate the tensile failure process of rock bridge with multi-crack. The general finite element software can only simulation continuous medium, in this paper we succeeded in discontinuous problem with this finite element software. Reach a conclusion of the rupture results of rock bridge in rock mass with multi-crack under the conditions of uniaxial compression, and the law of the stress distribution in the process of destruction.
