We review notations for, along with ways of presenting, the shear stress responses to large-amplitude oscillatory shear flow (LAOS). We find that the Fourier loss and storage viscosities to be the simplest primal notations for interpreting LAOS. The relative intensities provide the best evidence for oscillatory shear entering the large-amplitude regime. Deviation from linear viscoelastic behaviors can be observed through the distortions of Lissajous loops. We explore these loops in their elastic and viscous projections. The centerpiece of this work is our review table, which summarizes experimental measurements for polymer melts and solutions, targeting 21st century publications. Our review also provides conversion formulae to go from any of many notations to the Fourier loss and storage viscosities. The review table also defines which part of the LAOS measurement field has yet to be ploughed and shines light on which notations have been used, and for which purposes, to interpret nonlinearities.

非线性振荡剪切流符号和表示法的综述:聚合物液体

我们回顾了有关表示形式的剪应力对大振幅振荡剪切流(LAOS)的响应方式。我们发现傅立叶损失和存储粘度是解释LAOS的最简单的原始符号。相对强度为振荡剪切进入大振幅状态提供了最佳证据。通过利萨如环的变形可以观察到线性粘弹性行为的偏离。我们在弹性和粘性投影中探索这些回路。这项工作的核心是我们的审查表,该表总结了针对21世纪出版物的聚合物熔体和溶液的实验测量结果。我们的评论还提供了从许多符号到傅立叶损耗和储存粘度的转换公式。
