A mechanical method-Cellular element method was discussed. In this method the integer analysis of structure is changed into a series of part analysis by using the idea of Cellular Automata. It may have a good future in the aspect of large structures because it hardly has any special request on the capability of computer. Simultaneity, It can be developed into a high parallel arithmetic to suit for the request of parallel computer in the future. Therefore, the method is a good numerical method with great potential and can be used to solve the problems in analysis of large structures and nanostructures. The basic principle was introduced in this paper. It was applied to study plane problems. The computing steps and results were presented. Based on the numerical results, the feasibility and advantages of cellular element method were discussed.
