It is shown that construction material changes its properties as a result of operational loads action. There are situations when construction leaves its working state with satisfactory material characteristics. This is due to the process of formation and development of cracks as structural elements. The article proposes to analyze history of the development process, which makes it possible to study mechanisms of its flow and to determine factors of process control. The analysis of the studies carried out on the effect of prescriptional and technological factors on the properties of materials and products, the phenomena of self-organization and the role of cracks in materials and products showed that the emergence of critical events cannot be foreseen when assessing properties accepted by averaged characteristics. The construction is considered to be a complex self-organizing system. This determined the work aim: to justify the choice of dynamic models, allowing to determine the structure elements, interaction of which ensures functional state of the structure. The qualitative method of verbal description of the structure of systems with the use of cognitive approaches was laid in basis of adopted methodology. Conservative, metastable and active elements are distinguished in the construction-system. It is emphasized that the active history of the system is determined by active elements, to which cracks refer to. Cracks are considered as some necessary structural elements, present at all scale levels. It is shown that the formation of cracks-systems, treated as parasitic systems, terminates the end of construction-system development and the beginning of parasite system development. Completion of crack-system life cycle removes the construction-system from its working state. To get constructions with a given set of structural elements, a creative community of materials and designers is needed, which will create a common terminology dictionary for both specializations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
