The dynamic transient elastic-plastic response of the free-free beam subjected to normal and oblique impact at any cross section along the length of the beam is reported in the study. Total Lagrangian finite element formulation has been adopted together with the Newmark's time integration algorithm to obtain response of the beam. The contact force has been evaluated using the elastic-plastic contact law. The different modes of beam bending behaviour depending on the impact position of the beam have been discussed. The beam shows its stiffest behaviour against bending when the load is applied at 0.3L (L = half-length of the beam) from the free end. However, the beam becomes flexible in bending when the load is applied either at free end or at mid-span. The variation of impact energy, the energy gained by the beam and energy used in elastic-plastic deformation is also discussed. |
