6. Conclusion This study is focused on the experimental and numerical study of the mechanical behavior of an aluminum sheet at different strain rates and temperatures. The experimental results show the effect of strain rate and temperature on the behavior of the studied aluminum sheet. These effects are manifested by the variation of mechanical quantities like: tensile strength, elongation at break. The proposed extension of the GTN model to take into account the effect of anisotropy and strain rate gives a good capability to reproduce the experimental curves. References Aravas, N., 1987.
