Study of the influence of the hardening rule on a multi-step global manufacturing process modeling.

Energy consumption during manufacturing is a key element for the environmental impact assessment in modern industry. In order to optimize and avoid undesirable residual deformations final product an overall process, it necessary correctly identify variables that describe state of matter. This will allow recreate interaction existing between individual process global chain. Numerical simulations results chain combined solicitations, using different hardening rules same material, show importance this choice when simulation successive processes foreseen.
