Savchenko O. Optimization models and methods for deformed dissipative structures from composite materials under dynamic loads

The system approach is applied to the resolution of the optimization problem for complex dissipative composite structures with layers of viscoelastic and electroviscoelastic materials working under dynamic loads. This approach implies the implementation of several main stages: obtaining the effective modules matrix that adequately represents the properties of the composite material under dynamic loads; constructing the mathematical model of vibration for the dissipative structure, using a semi-analytical finite element method variation in the integral Fourier transform space; developing an optimization method based on genetic algorithms; defining an optimization parameters vector, restrictions on optimization parameters and optimality criteria, and developing software that implements the iterative optimization process for a structure that has to satisfy the designated criteria, particularly high energy dissipation level.
