In forming processes such as extrusion, the quality of the product depends in a complex manner on the parameters governing the process. For example, when plastics are extruded, severe swelling and shape change occur as the material emerges from the die. The equations describing such processes are extremely complex. The research to be carried out is aimed at developing a computational scheme uniquely suited to solving these equations. This scheme can aid in identifying parameters which most affect the formed product and perhaps eventually serve as a tool in process control.

在挤压等成型过程中，产品的质量以一种复杂的方式取决于控制该过程的参数。例如，当塑料被挤出时，当材料从模具中出来时，会发生严重的膨胀和形状变化。描述这种过程的方程式极其复杂。将开展的研究旨在开发一种唯一适合于求解这些方程的计算方案。该方案可以帮助确定对成形产品影响最大的参数，并可能最终作为过程控制的工具。
