ASTM WK69512

    Revision of E1820 - 18ae1 Standard Test Method for Measurement of Fracture Toughness

    (What is a Work Item?)

    Active Standard: E1820 - 20b

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



    WK69512


    Keywords

    crack initiation; crack-tip opening displacement; CTOD; ductile fracture; elastic-plastic fracture toughness; fracture instability; J-integral; JIc; KJic; Jc; δc; plane-strain fracture toughness; resistance curve; stable crack growth;;

    Rationale

    Since its introduction, E1820 has required the resistance curve procedure (single specimen) to be used in order to determine a J-R curve or a -R curve. The proposed revisions in this ballot would permit resistance curves to be determined using a collection of individual data points from multiple specimens.
