Crack-Resistance Curves of Surface Cracks in Alumina

The resistance of coarse‐grained alumina to stable crack growth, initiated from “naturally’occurring surface flaws, was studied in strength tests with a bend‐bar technique. The surface cracks experienced R‐curve behavior over the first few hundred micrometers; i.e., the applied crack driving force h...
