Researches :: Methods of mathematical modeling and computing experiment for maintenance of durability of materials and constructions, safety of complex systems and objects

Mathematical model of an emergency of technical systems that takes into account processes of the degradation of parameters, the accumulation of damages, the kind of a limiting condition and scripts of development of the accident is developed. The circuit of modeling of intense — deformed condition of constructions in conditions of a developing emergency is offered. Classification of types of emergencies and features of general and local intense — deformed condition of construction elements of potentially dangerous objects is carried out.
The statistical analysis of service defectiveness is executed and models of distributions of sizes of cracks in load-bearing constructions of transfer cranes and bridge cranes are developed. Taking into account stochastic nature of defectiveness probabilistic parameters of intense — deformed conditions of typical elements of constructions are received with the help of numerical methods. The comparative analysis of intense — deformed condition received with the help of analytical and numerical methods is made for typical elements of constructions. Thus significant distinctions both of intense conditions, and of the design life before the destruction are revealed. A series of design studies on strengthening and modernization of constructions of transfer cranes, bridge cranes and other high-loaded constructions having service damages is executed. According to the agreement between American Society of Mechanic Engineers (ASME International) and ICM SB RAS the development of electronic textbooks for students of technical specialities of Institutes of Higher Education and engineers is been carrying out. Each textbook contains test questions with multiple answers, explanatories and references to the detailed description of a specific theme. Within the framework of the contract works on creation of 5 electronic manuals are conducted: Finite element analysis, Material science, Electric circuits and electronics, Fluid mechanics, Thermodynamics. Simultaneously with the English version Russian versions of textbooks which are supposed to be used for training students of Krasnoyarsk Institutes of Higher Education are developed.
