Unexpected result shows that in some cases, pulling apart makes cracks in metal fuse - Sagittarius - 10-10-2013
Quote:It was a result so unexpected that MIT researchers initially thought it must be a mistake: Under certain conditions, putting a cracked piece of metal under tension — that is, exerting a force that would be expected to pull it apart — has the reverse effect, causing the crack to close and its edges to fuse together.http://web.mit.edu/newsoffice/2013/tension-can-fuse-metal-1009.html#.UlUNmWxxCzs.reddit
Interesting.
