An Investigation into Crystallization and the Subsequent Inelastic Response of Semi-Crystalline Polymers from a Continuum Perspective

半结晶聚合物在工业中有多种用途，因为它们能够承受大的变形，同时保持其韧性。这些聚合物的机械、电学和光学性能受其加工条件的影响;特别是温度诱导结晶。起主要作用的一个因素是由温度诱导结晶引起的材料对称性的突变。一个理论上严格的框架，研究温度诱导结晶正在开发中。这个框架提供了一个基础的可靠的数值预测，影响了一些工业应用，包括纤维纺丝，吹膜，模塑和挤出工艺。

Semicrystalline polymers find a variety of uses in the industry due to their ability to undergo large deformations while retaining their toughness. The mechanical, electrical, and optical properties of these polymers are affected by their processing conditions; in particular the temperature induced crystallization. One factor tat plays a major role is the abrupt change in material symmetry caused by temperature induced crystallization. A theoretically rigorous framework for studying the temperature-induced crystallization is being developed. This framework provides a basic for reliable numerical predictions that affect a number of industrial applications including fiber spinning, film blowing, and molding and extrusion processes.
