    Abstract

    Tests were made to compare Kc values for Alclad® 7475-T761 determined from 16-in. (406-mm) wide, center-cracked tension panels tested with and without guides designed to prevent buckling from intensifying the crack tip stress field. The tests show that for sheet thicknesses ranging from 0.06 to 0.15 in. (1.52 to 3.81 mm) a multiplication factor of 0.87 is required to convert Kc values obtained employing antibuckling guides to corresponding values obtained without guides. Above 0.15-in. thickness, test panels appeared to be of sufficient stiffness to prevent buckling without the use of guides, and therefore the conversion factor is unity.
