Résumé :

Mathematical models are more and more used to simulate law mechanical of materials.In this work, genetic algorithm (GA) [1] was performed to determine the law of tensile mechanical behavior of low density polyethylene (LDPE), for a uniaxial tensile test .The parameters taken into account are the constraints based deformation for temperatures as 25 ° C and a strain rate included between 5.10-3s-1 and 50.10-3s-1 . . Our simulation results are compared with experimental work.To do this, and to approach the law of the mechanical behavior of the material used in our work, we opted for the method of genetic algorithm , or GA, as a method of simulation, we have applied to LDPE.
