| Abstract: | Experimental researches and computer simulations are presented on dynamics behaviors of free-free tubes laterally impacted by flat-nosed cylindrical missiles at the mid-point of their spans. For free-free tubes with different diameters, lengths and material properties, the deformation processes, final modes and energy distributions are studied, which are compared with those of free-free beams. Simultaneously, the critical velocities and kinetic energy of the missiles are obtained when the free-free tubes are penetrated. |
| Keywords: | free-free tube computer simulation deformation mode critical velocity |
