The behavior and fracture of complex structures under dynamic loading conditions were studied by computer simulation using the method of mobile cell automats. Possibility of the effect of elastic energy accumulation is demonstrated. The character of fracture in the systems studied can be considerably modified by very slightly changing initial geometry of the structure.

Behavior and peculiarities of failure of frame structures under dynamic loading are studied on the basis of computer modeling. The advantages of the Movable Cellular Automata (MCA) method allow to study all stages of the fracture process from damages generation to the complete failure. A possibility of the effect of elastic energy accumulation in complex structures is shown.

A new promising numerical method named movable cellular automata (MCA) is described. Because this approach is based on the discrete concept, in contradistinction to FEM-based software, the software based on the MCA concept has a few clear advantages. The main one is connected with modeling of real fracture process. The MCA method has been successfully used for modeling dynamic loading of heterogeneous materials and structures. The results of simulations agree closely with the experimental data. The results show that the MCA approach could be really useful to solve a lot of civil engineering problems from materials to constructions. Special software has been developed on the basis of this method. Due to its potentially unique abilities, the MCA method could be considered as a breakthrough in numerical techniques and a new tool of engineering mechanics.

Capabilities of the movable cellular automata (MCA) method for computer simulation of three-storied structures for the purpose of increasing their strength characteristics are considered using simulated seismic loading of these structures as an example. Architecture of an intellectual electronic dynamic monitoring system for acquisition, storage, communication and processing of the data of full-scale experiments on fracture of real structures is proposed. Further application of this system in the movable cellular automata method to predict vulnerability of these structures is discussed.

A new promising numerical method is described. The method is based on the physical mesomechanics and referred to as the movable cellular automata (MCA) method. Since the methods proceeds from the discrete approach, the MCA-based software has a few clear advantages over that relying on the finite element method (FEM). The main merit consists in the fact that the method allows for modeling a real fracture process. The MCA method has been successfully used to model dynamic loading of heterogeneous materials and structures. The results of simulations agree closely with the experimental data. The capabilities of the MCA approach are demonstrated on the basis of inhomogeneous materials and structures. The results show that the MCA approach could be very useful in solving a great number of mechanical engineering problems ranging from the problems of materials science to calculation of the whole structures. A special software could be developed on the basis of this method. Due to its potentially unique abilities, the movable cellular automata method is considered a breakthrough in numerical techniques and a new tool for engineering mechanics. The MCA method is a very promising computational technique that allows one to study the objects where experimentation or direct measurement are not possible.
