ITHACA, N.Y. -- A tiny, invisible crack in the aluminum-alloy skin of an airplane can sometimes grow into a major crack that causes the skin to tear open in flight. A new research program at Cornell University aims to understand how this happens, starting at the level of atoms and working up. Eventually this understanding could lead to improved alloys and designs to prevent cracking and failure in many materials.
The above story is based on materials provided by Cornell University. Note: Materials may be edited for content and length.
