Beta relaxation in the shear mechanics of equilibrium viscous liquids: Phenomenology and network modeling of the alpha-beta merging region
摘要：
的β松弛过程中的玻璃形成液体的剪切力学响应的现象学进行了总结和比较的介电β过程。此外，我们讨论了如何通过标准的粘弹性建模元素的观测建模。必要的物理要求，这样一个模型的概述，有人认为，物理相关的模型必须添加剂的α和β部分的剪切顺应性。基于这些考虑提出了一个模型，并拟合聚异丁烯680的数据。
英文摘要：
The phenomenology of the beta relaxation process in the shear-mechanical response of glass-forming liquids is summarized and compared to that of the dielectric beta process. Furthermore, we discuss how to model the observations by means of standard viscoelastic modeling elements. Necessary physical requirements to such a model are outlined, and it is argued that physically relevant models must be additive in the shear compliance of the alpha and beta parts. A model based on these considerations is proposed and fitted to data for Polyisobutylene 680.
