ASTM WK24730

    Revision of C769 - 98(2005) Standard Test Method for Sonic Velocity in Manufactured Carbon and Graphite Materials for Use in Obtaining an Approximate Young's Modulus

    (What is a Work Item?)

    Active Standard: C769 - 09

    Developed by Subcommittee: D02.F0 | Committee D02 | Contact Staff Manager



    WK24730

    1. Rationale

    This standard reports a method for the determination of Elastic Modulus from the sonic velocity of a longitudonal wave. We wish to add the measuremnet of the shear wave velocity such that both the shear modulus and Poissons ratio can be determined. A round robin will be initiated for the propsed shear velocity method.
