- Abstract
- The brief reviews one method of analyze of numerical solution for thin-walled skins dynamic tasks. Solution was obtained by using of finite element method and finite difference forth degree Runge-Kutta method. Numeric solution of prediction functions were obtained. These functions have view of analytic solution. Recommendations for choosing of time step of integration are presented. For free and forced vibrations numerical instability is estimated. Functions of prediction of numerical solutions are compared with analytic solutions and results of numeric experiments.
