Numerical simulation of the anisotropic behavior of 2017 aluminum alloy

Analyses about the Anisotropic Behavior of a 2017A Aluminum Alloy

“…In the following illustrations, the results obtained from simulations using the parameters identified by the authors of [2] are shown with red marks. The curves presented with blue marks correspond to simulations obtained by exploiting the parameters identified by the authors of [1], whereas our experimental results are in green. The comparison between the simulation and the experimental one is presented on the figures.…”

“…This new version of the model includes 17 parameters in the most general version taking into account the viscous effects, both types of hardening, non-proportional loading, strain hardening memory ... In 2012, an extension of the model is carried out in [1] which takes account the anisotropy of the extruded aluminum alloy 2017A. In 2015, Taleb et al [2] performed a new identification of material parameters using a large database of strain controlled experiments.…”

“…Two sets of parameters were used. The first set is proposed in [1]; it is identified considering cyclic tests performed under strain control following proportional and non-proportional paths. The second set of parameters has been identified recently on a larger database [2].…”

Experimental Analyses about Ratcheting of Extruded 2017A Aluminum Alloy Subjected to Proportional and Non-Proportional Loadings

“…Therefore, despite the large number of works carried out, the cyclic behavior of metals remains not completely understood especially for "not yet standard metals" like anisotropic aluminum alloys. Indeed, only few studies may be found in literature about the cyclic behavior of this type of alloys subjected to multiaxial loading conditions where several directions of anisotropy may be activated under strain control [4][5] or stress control [6]. Furthermore, the anisotropy considered in these studies is often about rolling aluminum sheets while other anisotropies due to other processes like extrusion deserve investigations.…”

Fatigue of Extruded 2017A Aluminum Alloy Subjected to Non-Proportional Loading Paths

“…Despite the large number of works available in the literature, the cyclic behavior and fatigue of metals remain not completely understood especially for anisotropic metals like extruded aluminum alloys. Indeed, only few studies may be found about this type of alloys subjected to multiaxial loading conditions where several directions of anisotropy may be activated under strain or stress control [2][3]. Furthermore, the anisotropy considered in these studies is often about rolling aluminum sheets while other anisotropies due to other processes like extrusion deserve investigations.…”
