要約

The solution to the nonlinear unsteady loading problems of multi-element structures using time steps and the implicit difference scheme is considered. Attention is focused on reducing computational costs and improving the modeling accuracy of structural damping. A variant of the method with substructures is proposed to solve the nonlinear unsteady loading problems.
