Movable cellular automaton

The movable cellular automaton (MCA) method is a method in computational solid mechanics based on the discrete concept. It provides advantages both of classical cellular automaton and discrete element methods.

Important advantage of the МСА method is a possibility of direct simulation of materials fracture including damage generation, crack propagation, fragmentation and mass mixing. It is difficult to simulate these processes by means of continuum mechanics methods (For example: finite element method, finite difference method, etc.), so some new concepts like peridynamics are required.

Discrete element method is very effective to simulate granular materials, but mutual forces among movable cellular automata provides simulating solids behavior.

If size of automaton will be close to zero then MCA behavior becomes like classical continuum mechanics methods.
