This slow-motion movie has kindly been provided by Sanjeev Sharma and Richard Dashwood of the International Manufacturing Centre, WMG University of Warwick. It shows two samples designed to absorb energy in a head-on collision. On the left is a glass-filled nylon composite material with a 5xxx series aluminium back plate, which is to be compared against a 2.5 mm thick 5xxx series aluminium alloy on the right. Both tests are done at 14.7 m/s providing an 8 kJ impac. The movies are recorded at 5400 frames per second and played at 30 frames per second. The metallic component on the right crushes systematically whereas the composite shatters. Both absorb the impact, which last for a mere 0.03 s. http://www.msm.cam.ac.uk/phase-trans
