Abstract
The dynamic compressive properties of Dyneema have been investigated using a dropweight machine. The mechanical behaviour was monitored using high-speed photography and a force transducer. There was considerable variation in behaviour shot-to-shot, but all the specimens of this material were observed to shatter in this apparatus. Stress-time plots showed multiple failures on a timescale of approximately 0.2 ms interval.
