Snapshots of small scale drop tests (1/16) for different objects with a penetration depth of 0,02 m and the following characteristics:
• (a) : cone 20° with a drop height of 1,00 m
• (b) : cone 45° with a drop height of 1,50 m

The movies show tests performed by Ghent University:
• Large scale drop tests performed at the “Watersportbaan”.




• Large scale drop test filmed by a high speed camera.


• A destruction test which has been carried out on a large scale model (1/3).
Remark: the playback of the video is accellerated by a factor of 10.
