A simplified key-curve approach for J-R-curve testing of CT-specimens

Kim Wallin

    Research output: Book/ReportReport

    Abstract

    A novel key-curve based procedure for crack length measurement on CT-specimens is presented. The procedure is compared with other testing methods for three different pressure vessel steels. The new procedure is shown to yield accurate enough results for normal J-R-curve testing. Different causes affecting the accuracy of the method are discussed.
