Some Geometric and Component Interaction Effects during the Axial Collapse of Glass/Polyester Tubes at Force Levels Compatible with Rail Vehicle Design

  • John F. Kelly


Glass/polyester tubes can be triggered into stabilised axial collapse at force levels at least up to 2 MN whilst obtaining energy density levels up to some 58kJ/kg. The geometric arrangement of the tube influences the triggering force, energy density and debris flow during collapse although multi-tube arrangements, in equilateral triangular arrays, do not appear to affect performance. These devices can offer commercial and technical advantages in rail vehicle applications.
