Hybrid particle-element simulations of impact, perforation, and fragmentation.
A great video on YouTube from the Cockrell School of Engineering, in partnership with the Arctic Region Supercomputing Center (ARSC) at the University of Alaska Fairbanks and the Department of Defense’s High Performance Computing Modernization Program’s (HPCMP) Data Analysis & Assessment Center (DAAC), shows visualizations of a simulation of high-velocity impacts.
The video shows 2 impacts in particular:
- a 10mm Aluminum Sphere impacting a 2.5mm Aluminum Plate at 6.7km/s
- a 7.67mm Uranium Alloy Rod impacted a 6.4mm Plate obliquely at a 73.5 degree angle, at 1.2KM/s
The visuals are pretty, and a bit hypnotic to watch. The video is also the proud recipient of one of the recent SciDAC Visualization Night OASCR’s.
