A New Computational Technique For Analyzing Deformation Processes of Rheologically Complex Materials

在挤压等成形过程中，产品的质量以一种复杂的方式取决于控制过程的参数。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。描述这类过程的方程极其复杂。要进行的研究旨在开发一种独特的适合于求解这些方程的计算方案。该方案可以帮助识别最影响成形产品的参数，并可能最终作为过程控制的工具。

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.
