5. Identification of behavior law parameters

We saw in paragraph 2.1 that a key problem was the choice of behavior law ("fluid" or "solid" type). Briefly, we can consider that :

  • in processes where processing starts from the liquid state (a parison of extruded polymer that is blown), it is reasonable to consider a law of liquid behavior (Newtonian in the first approximation, then viscoelastic);...
