论文摘要
粘弹性应力松弛是软物质系统（例如胶体，凝胶和生物网络）的基本特征。尽管线性粘弹性的麦克斯韦模型提供了应力松弛的经典描述，但麦克斯韦模型通常不足以捕获软物质的复杂松弛动力学。在本教程中，我们介绍并介绍了在软材料中观察到的非马克斯威尔线性应力松弛的物理学，这种效应在不同系统中的归因起源，以及可用于捕获这种放松行为的适当模型。我们提供了一个基本的工具包，可以帮助理解和建模软材料的机械放松，以用于不同的应用。
Viscoelastic stress relaxation is a basic characteristic of soft matter systems such as colloids, gels, and biological networks. Although the Maxwell model of linear viscoelasticity provides a classical description of stress relaxation, the Maxwell model is often not sufficient for capturing the complex relaxation dynamics of soft matter. In this Tutorial, we introduce and dis-cuss the physics of non-Maxwellian linear stress relaxation as observed in soft materials, the ascribed origins of this effect in different systems, and appropriate models that can be used to capture this relaxation behavior. We provide a basic toolkit that can assist the understanding and modeling of the mechanical relaxation of soft materials for diverse applications.
