| A series of tensile tests on uniaxial specimens machined from different orientations with respect to the rolling direction was carried out at a wide range of loading rates for an aluminium 7017-T73 alloy. The experimental results revealed a high degree of anisotropy on both yield stress and plastic flow. In addition, the material showed very little strain-rate sensitivity. The measured fracture strains for different loading orientations showed large differences. In order to describe the material behaviour, the Yld2000-3d yield criterion and an isotropic Voce hardening model were used to describe the plasticity of the AA7017-T73. Finite element simulations showed that the plasticity model provided accurate predictions of local and global material responses under uniaxial loading. A Cockcroft-Latham failure criterion was presented for describing the anisotropic fracture behaviour of the AA7017-T73 | |
