INTERRELATION OF STRUCTURES OF PRODUCT AND MATERIAL

Abstract
In the article building products are explored as the open self-organized system. Such representation allows revealing interrelation between organization of the structure of product and the structure of material. The material is considered as hierarchy of autonomous conditional levels of structural heterogeneities. Formation of integrated structure of the product-system is a result of initiation structural changes by levels. It promotes emergence of various structures at levels of heterogeneities. The interrelation of levels is provided by self-development of networks of technological cracks and inner surfaces of partition. Interaction of active elements allows to be shown to properties at the level of a product and to effects of adaptation of material to influence of external factors. Formation of the ordered set structural elements will promote increase resistance of a product under operating conditions. It is possible to operate the structural organization of material and a product due to change of macrostructure parameters.
