To characterize the material, tensile tests were carried out on plane samples cut in the three orthotropic directions 0°, 45°, and 90°. Then, the behavior of the AlMgMn aluminum alloy is studied at different strain rates and temperatures. In terms of numerical modeling, the physical model of Gurson, Tveergard, and Needleman extended to take into account the orthotropic thermos viscoplastic behavior of AlMgMn aluminum alloy is used to realize the numerical part of this work. This model was successfully implemented in Abaqus/Explicit using the Vumat subroutine. Thereafter, numerical simulations were performed to compare the predictions of the implemented model with the experimental results. The results obtained showed that the model reproduces correctly the orthotropic thermo-viscoplastic behavior of the material studied. © 2023 The Authors. Published by ELSEVIER B.V.
