CELLULAR AUTOMATA MODEL TO SIMULATE ROCK THREE POINT BENDING TEST
Cellular automata are mathematical models that express self-organization process of the whole system owing to nonlinear interaction among local elements inside the system by constructing simple rules. In this paper a cellular automaton model is presented to simulate rock failure. Force and displacement are taken as the basic state variables. Based on the basic mechanical laws vector updating rules are constructed, which overcomes the shortcomings of arbitrary decision of local rules and scalar variables. Based on this model fracture process of thrcc-point-bend samples was simulated. The influences of pre-existing cracks on the fracture process of three-point-bend samples were studied. The stress-strain curves corresponding to the fracture process were attained.
