Abstract

In the article, the methods of vibrations and dynamic stability analysis of bars having the nonlinear diagram deformation of material are suggested. The example of calculation of a bar with hinged supports of ends is given. The graphs of bar deflection as a function of time parameter are constructed.

Keywords

physical nonlinear, free vibrations, dynamic stability, parametric optimization, genetic algorithm, adaptive operators, mutation, crossover, inversion
