RIA: Studies of the Constitutive Behavior of Amorphous Thermoplastics

这个RIA奖将调查，无论是实验和 解析地，各向异性和各向异性屈服。 的 发生在无定形聚合物中，由于分子排列（或 取向或纹理）。 在此基础上，建立了一个精确的本构关系， 它密切地描述了实验观察到的 各向异性屈服 这种关系将有助于 随后的制造工艺研究， 材料经历大的非弹性变形。

This RIA award will investigate, both experimentally and analytically, the anisotropy, and anisotropic yielding. That occurs in amorphous polymers due to molecular alignment (or orientation, or texture) that is produced during deformation. Based on that study, an accurate constitutive relation will be developed that closely describes the experimentally observed anisotropic yielding. Such a relationship will be useful in subsequent studies of manufacturing processes in which such materials undergo large inelastic deformations.
