This Small Business Innovative Research Phase I project involves development of asoftware for an accurate simulation of polymer co-extrusion. The new co-extrusion software will use a unique proprietary constitutive theory, which can accurately capture the complex rheological behavior of polymers. The three-dimensional mesh of tetrahedral finite elements in the co-extrusion system will remain unaltered during the co-extrusion simulation. Instead of requiring the interface between different polymers to match with finite element boundaries, the interface will be allowed to cut through the finite elements. The new software will provide design engineers as well as engineering students a useful tool to perform numerical experiments for optimization of co-extrusion systems. Many different types of companies, including plastic material suppliers, plastic part manufacturers and extrusion equipment manufacturers, will be able to cut cost and increase revenues using this software.

这个小型企业创新研究第一阶段的项目包括开发用于精确模拟聚合物共挤出的软件。新的共挤出软件将使用独特的专有本构理论，可以准确地捕捉聚合物的复杂流变行为。共挤压系统中四面体有限元的三维网格在共挤压模拟过程中保持不变。不再要求不同聚合物之间的界面与有限元边界相匹配，而是允许界面穿过有限元。新的软件将为设计工程师和工程学生提供一个有用的工具来进行优化共挤压系统的数值实验。许多不同类型的公司，包括塑料材料供应商、塑料零件制造商和挤出设备制造商，将能够使用该软件降低成本并增加收入。
