聚合物加工的研究通常集中在研究给定材料和技术的加工/结构/性能关系，讨论设备的进步，或过程分析和模拟。这最后一个方面在过去几年中受到了特别的关注，因为提供有效的工具来帮助设计和优化活动是很重要的。给定过程的模拟通常包括三个主要步骤：
对过程的物理理解和数学模型的发展;
对于给定的系统几何形状和操作条件，求解与材料的本构律耦合的相关控制方程;
将现有的实验数据与模拟预测进行比较，以评估模型的适当性，并最终改进模型。然后，该程序可以放心地用于工程目的。
Research in polymer processing usually concentrates in studying processing/structure/properties relationships for a given material and technology, in discussing advances in equipment, or in process analysis and simulation. This last aspect has received particular attention in the last few years, as it is important to make available efficient tools for assisting design and optimisation activities. The simulation of a given process usually involves three main steps:
the physical understanding of the process and the development of a mathematical model;
solving the relevant governing equations coupled to a material’s constitutive law, for a given system geometry and operating conditions;
comparing the available experimental data with the simulation predictions, in order to assess the adequacy of the model and, eventually, improving it. The programme can then be used with confidence for engineering purposes.
