Maybe. On the other hand, where does the released strain energy go when a crack happens? If it goes into extremely localized heating, it could thoroughly scramble the structure for several microns on both sides of the crack. -- Keith Lynch, http://www.access.digex.net/~kfl/ Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=4788
