The Calculation of Plastic Component of CTOD Inconsideration of Crack Extension

    Graphical Abstract
    • Abstract
  • For the problem of dimension inconsistency in calculationof plastic component of CTOD (δp) given by the current standards， the formula of δp is deduced based on the plastic hinge model in consideration of crack extension. The correct formula is obtained and the deviation caused by the technical error is analyzed.
