The Fracture Toughness Round Robins in VAMAS: What We Have Learned

Published

Author(s)

George D. Quinn

Abstract

Over the last thirteen years the Versailles Advanced Materials and Standards (VAMAS) project has conducted five full fledged, international round robins on ceramic fracture toughness characterization. As many as forty laboratories have done thousands of experiments on silicon nitride, silicon carbide, zirconia, alumina, zirconia-alumina, zirconia-alumina composite, and whisker-reinforced alumina. Methods include single-edged V-notched beam, chevron notched beam, surface crack in flexure, indentation strength, and indentation crack length. Highlights of these projects will be presented along with some lessons learned about round robins in general.
