TNO – FN Herstal

DTRL contributed to a research & development program on less-lethal ammunition using gel material by performing tensile tests at low, intermediate and high speed. High speed camera image analysis is applied to determine the material strain and strain rate. The strain rate dependent material behaviour was derived from the experiments and applied to fit an appropriate material model for Finite Element simulations, including visco-elastic behaviour. At high tensile velocities the moving stress wave is clearly visible.

12 m/s tensile velocity
1.2 m/s tensile velocity
Methods used:

  • High strain rate tensile testing
  • High speed film analysis
  • Image processing
  • Visco-elastic material model fit in LS-Dyna
