New Advanced Ceramics Standards from ASTM Cover Fracture Mirror Size Analysis, Tensile Strength DataSubcommittee C28.01 on Mechanical Properties and Performance, part of ASTM International Committee C28 on Advanced Ceramics, has recently approved two new standards, ASTM C1678 , Practice for Fractographic Analysis of Fracture Mirror Sizes in Ceramics and Glasses, and ASTM C1683 , Practice for Size Scaling of Tensile Strengths Using Weibull Statistics for Advanced Ceramics., ASTM C1678 —Bringing Consistency to Fracture Mirror Size Analysis, Fracture mirror size analysis is a powerful quantitative tool for the interpretation of broken ceramic and glass articles. While this type of analysis can be used to determine the stress in a part at the instant of fracture, inspection and interpretation procedures have often varied, resulting in uncertainty in stress estimates. ASTM C1678, Practice for Fractographic Analysis of Fracture Mirror…, ASTM C1683 —Scaling Strength Values, ASTM C1683, Practice for Size Scaling of Tensile Strength Using Weibull Statistics for Advanced Ceramics, provides methodology to convert fracture strength parameters estimated from data obtained with one test geometry to strength parameters representing other test geometries. Stephen Duffy, chair of civil engineering, Cleveland State University, and C28 member, says that companies producing…
