The main objective is to model the plastic behavior of the three aluminum alloys 1050, 2024 and 7075.In the first part, using the experimental results of uniaxial tensile tests for each alloy and in the three main directions, and using a strategy of identifying the parameters of each work hardening model studied, Hollomon, Swift and Voce, we have created an empirical database of 1050, 2024 and 7075 aluminum series alloys.In the second part, one established the curves of uniaxial tensile curve by using the work hardening laws and the experimental parameters obtained in the first part. The comparison with the experimental data shows that the plastic behavior model can successfully describe with the use of appropriate workhardening law for each alloy.
