This test setup can be used to investigate the propagation of cracks in rocks (e.g. after blasting work or meteorite impact).

• Sample size up to 250*250*50 mm
• Sample holder can be used several times, samples can then be removed completely "as a whole"
• Effective principle equivalent to flyer-plate, but with elongated flying plates (size adapted to sample size)
• initialisation by modified PWG, flying plate speeds < 1 km/s
• internal impedance correction by inserting plywood
• rock parameters according to Ahrens & Johnson (1995) [1]
