Standardization of Fracture Toughness Testing of Ceramics in the United States

Published

Author(s)

George D. Quinn

Abstract

American Society for Testing and Materials (ASTM) standard test method PS 070 has been created for fracture toughness of advanced ceramics. It includes three test methods which use beams in bending: chevron notch (CNB), single-edged precracked beam (SEPB), and surface crack in flexure (SCF). Supporting data has been collected through several Versailles Advanced Materials and Standards round robins. This paper discussed the evolution of the standard including the rationale for the choice of the three methods and the specifications in the standard. Progress on Standard Reference Materials #2100 which will have certified values of fracture toughness will be presented.
