“…As an application of the autonomous behaviour, the concept of the intelligent autonomous element method is also shown. In numerical examples, by using the intelligent autonomous element method, the optimum sectional areas of the truss member of the minimum volume truss under the given constraints and the geometric analysis of variable geometry trusses by a knowledge-based approach were shown in References [11,12]. However, the systematic autonomous decentralized approach was not mentioned explicitly, because their purpose was limited to an analysis using the object-oriented approach.…”

SUMMARYIn this paper, a new solution procedure using the ÿnite element technique in order to solve problems of structure analysis is proposed. This procedure is called the autonomous decentralized ÿnite element method because it is based on the characteristic autonomy and decentralization in life or biological systems (life-like approach). The fundamental approach is developed according to an idea of cellular automata manipulation by the new neighbourhood model. The ÿnite element method with an algorithm of the relaxation method is adopted as the solution procedure in this approach. The proposed procedure demonstrates that it is a powerful means of numerical analysis for many kinds of structural problems that are structural morphogenesis, structural optimization and structural inverse problems. Our procedure is applied to numerical analysis of three simple plane models: (1) The structural shape analysis problem for the prescribed displacement mode of a truss structure, (2) An adaptive structure remodelling problem on an elastic continuum, (3) An identiÿcation problem of thermal conductivity on a continuum. The e ectiveness and validity of our idea are shown from their numerical results.
