ASTM WK46984

    Revision of E1820 - 13 Standard Test Method for Measurement of Fracture Toughness

    (What is a Work Item?)

    Active Standard: E1820 - 13

    Developed by Subcommittee: E08.07 | Committee E08 | Contact Staff Manager



    WK46984

    1. Rationale

    The dimension for one half of the corrected crack mouth opening displacement is incorrectly identified as dc instead of dc/2 in Figure A2.3. The proposed revised figure corrects this error and provides a better description of the geometry involved in the rotation correction.
