Abstract:

A concept is described for using liquid metal embrittlement LME to cause fracture of steel. Three different approaches are taken to break the metal, all based on putting the liquid metal LM into a surface notch or groove and applying stress. Some success was achieved in breaking the metal in quasi-static tests of flat samples. However, for dynamic tests of flat samples, as well as tests of a specific cylindrical configuration, brittle fracture was not achieved.
