A mixed scheme of finite element method, numerical and analytical methods, including iterative method of artificial neural networks for solving mixed structurally nonlinear dynamics problems and boundary contact problems of resistance are developed. The influence of different types of defects on the stress-strain state and stability of composite structures based on refined models taking into account the transversal shear and compression is studied. The methods of parametric optimization are developed and the algorithms for solving problems of optimization of the total construction parameters and modes of manipulation and control model the technique of continuous monitoring of complex dynamic systems using linear and nonlinear aggregate operators are developed, quasi-systolic method of parallel computing for solving problems of digital filtering of any dimension is proposed. The results are used in the design of cellular structures by Corporation “Energoresurs-Invest”. Product Description popup.authors Бутитер І.Б. Гураєвська І.Є. Демидюк М.В. Когут І.С. Литвин Б.А.
