| description | The present paper deals with the numerical study of energy absorption of reduction tubes using a die subject to axial impact load. Non-linear finite element software LS-DYNA is employed to analyze the deformation pattern and energy absorption characteristics. The tubes, with the bottom ends constrained axially, deformed in necking modes by the axially moving dies. The geometries of the tubes and the dies were varied to find out the influence of the geometry parameters. The strain rate effect of the material is considered and the Cowper-Symonds equation is applied in the plastic dynamic analysis. |
