Abstract
This paper examines the method of direct design of structures, which is based on usage of the compiler founded by finite element method (FEM) and method of adaptive evolution (MAE). In this connection, the concept of the reference stress-strain state of the system formed by sequential build its energy equally strong counterpart is introduced. In this case, the refinement exposed, in general, not only the geometry, but also the physical and mechanical properties of elements. At the same time, it has the opportunity to varying characteristics such as coordinates of the bearing design, constraint type, load location, and others. The result of indicated approach is to build an energetic portrait of the system, including the definition of the system topology, characterized by a minimum value of the accumulated during deformation, potential energy and uniform (quasiuniform) distribution of potential energy density. In the above test examples illustrated approach priorities and features of derived implementations Relationship between known criteria of structure parameters rationalization and new ones introduced in this paper is denoted. Noticed reference stress-strain state of the system is the first approach of the formation of the final decision. Therefore, in the paper, based on the exploitation of Kieffer-Johnson method a sequence of procedures for its numerical implementation is revealed. Derived results are the basis for CAD algorithm design of structures with improved characteristics.
