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-

A fundamental field for the edge crack problem is suggested, and the field is composed of the singular displacement field and the complementary regular field. The boundary displacement of the fundamental field plays the role of the weight function in the edge crack problem. After multiplying the bou
