[Étude paramétrique de la cinétique de cristallisation de polymères semi-cristallins lors du refroidissement]
Au cours de l'étape de refroidissement lors de la transformation des polymères, le comportement du matériau est difficile à modéliser, a cause du couplage complexe entre les phénomènes de cristallisation, les transferts thermiques et les variations des propriétés du matériau. Ce travail porte sur la simulation numérique du couplage entre la cinétique de cristallisation et la cinétique des transferts thermiques, en l'absence d'écoulement et en utilisant la méthode des éléments finis.
During the cooling stage in several types polymer processing, the behavior of the polymer is very difficult to model and to simulate numerically, because of the complicated coupling between the crystallization process, the heat transfer and the material properties change. The aim of this Note is the numerical simulation of the coupling phenomena between the crystallization rate and the thermal kinetics in a semi-crystalline polymer during cooling without flow, by using Finite Elements Method.
