A green-label system and the European Composites Recycling Concept (ECRC) have been launched in the EU. Recycled materials (recyclate) are much more commonly used in North America. In Japan, the cement kiln process is being used with success, while chemical recycling technologies are being developed actively.

Galerkin, Méthode deEn mathématiques, dans le domaine de l'analyse numérique, les méthodes de Galerkine sont une classe de méthodes permettant de transformer un problème continu (par exemple une équation différentielle) en un problème discret. Cette approche est attribuée aux ingénieurs russes Ivan Boubnov (1911) et Boris Galerkine (1913).

Simulation par ordinateurIndex. décimale : 668.4 Plastiques, vinyles Résumé : A novel simulation technique for the flow in plastic mixers based on Element-free Galerkin Method (EFGM) has been developed in this study. To improve the simulation accuracy, a “rearrangement” scheme has been employed which eliminates errors caused by the irregular distribution of data points. Through several numerical tests, the new simulation technique has been validated to be applicable to high viscosity fluid flow with enough accuracy. Furthermore, simulation examples for realistic mixers were carried out using the developed technique. From the results, it was found that the developed technique is capable to investigate the relationship between flow behavior inside realistic mixers and operating conditions.

Titre : Viscoplastic material modeling for the stretch blow molding simulation Type de document : texte imprimé Auteurs : S. Wang, Auteur ; A. Makinouchi, Auteur ; M. Okamoto, Auteur ; T. Kotaka, Auteur ; M. Maeshima, Auteur ; N. Ibe, Auteur ; Takaharu Nakagawa, Auteur Année de publication : 2000 Article en page(s) : p. 166-175 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 668.9 Polymères Résumé : In this paper, the viscoplastic material model of PET (polyethylene terephthalate), which is intended to be used in the FEM (finite element method) simulation of stretch blow molding process, has been studied. Material tests of PET were performed with the constant strain rates varying from 0.01 to 1 (1/s), at temperatures ranging from 90 to 150°C, based on the obtained data a two-stage model was proposed. The proposed model could precisely take into account the effects of strain hardening, strain rate sensitivity, variation of the hardening index, and temperature dependency. This model has been implemented into the nonlinear finite element code PBLOW3D, which is developed in the Riken, and its performance in the stretch blow molding simulation has been studied. It has been demonstrated that the proposed material model provides significant improvements, compared with two existing material models, in the simulation of the blow molding process of PET bottles.
