On the fracture locus of AA7075-T651

Abstract: Abstract. The overall goal of this work-in-progress is to try to establish the fracture locus (i.e. the equivalent strain to fracture as a function of the stress triaxiality factor) for the high-strength AA7075-T651 aluminium alloy. Experiments on several specimen geometries enabled us to reach stress triaxialities in the range from ı* = 0 for shear tests to ı* = 1.4 for notched specimen tensile tests. For shear tests, failure occurred by strong strain localization. However, local stresses and strains can not … Show more
