Abstract

In this article is solved the plane problem of the dynamic behavior of an elastic beam loaded by static forces which cause instability. The finite element method (FEM) has been used to solve the nonlinear problem. Different cases of the dynamic behavior of the elastic beam loaded by gravity forces have been considered.

Keywords:

the finite strain, the nonlinear dynamic, stability, the finite element method.
