✦ Synopsis

closed-form equations are given for the plastic zone size and crack tip openingdisplacement in a circumferentially-cracked cylindrical bar under tension, treated in terms of a Dugdale-type modeI. The equations are valid from a lower limit of linear-elastic behaviour up to the intervention ofa limit-load failure mechanism. They have been derived by fitting a previously given set of set-ernpi~~l equations to finite-element data for this geometry, derived from the literature.
