| Abstract Scope |
Stress triaxiality is not sufficient to explain the effect of the stress state on the ductility of materials such as Al2024-T351. For such materials, a dependence of the fracture strain on the third invariant of the stress tensor deviator has been proposed. The investigation of ductile fracture under pure shear conditions offers the possibility to qualify shear-driven damage mechanisms and validate material modeling. Here, the influence of microstructural anisotropy on the shear behavior of Al2024-T351 has been systematically investigated with the compact forced-simple-shear (CFSS) sample geometry. A microstructural investigation was carried out on three tested samples whose shear planes are aligned to the rolling, transverse and normal directions. The load-displacement curves and the DIC strain maps were used to validate the plasticity damage self-consistent (PDSC) model, developed in the context of continuum damage mechanics, where the damage dissipation potential accounts for different damage mechanisms (intervoid necking, shearing, and sheeting). |
