Abstract
The paper describes the Finite Element Method (FEM) analysis of elastic plastic deformation of steel tube impact absorbers for railway vehicles. Experiment investigation is used as a base for FEM modelling and simulation. The developed FEM model includes material nonlinearity (plasticity), nonlinear contact and large deformation of finite elements. All of aspects used in the absorber FEM model are detailed explained. The Finite Element Analysis results for a chosen absorber are presented and discussed. Developed model opens the possibilities for next investigations in similar problems.
