本文的主题是在两机制模型（通常是多机制模型）的框架内对线性粘弹性经典描述的扩展。多机制模型主要用于描述塑性材料的行为。本文提出了一种基于两个Kelvin-Voigt体串联模型的粘弹性材料模型。与经典的流变模型相反，我们允许两个Kelvin-Voigt机构之间的相互作用。我们的模型是能够重现经典的线性粘弹性，包括相互作用定性预测材料的行为，如棘轮。我们强调这一点，通过提供定性的数值模拟的一维杆刺激的不对称的循环应力。
The subject of this article is an extension of the classical description for linear viscoelasticity within the framework of two-mechanism models (generally, multi-mechanism models). Multi-mechanism models are mainly used to describe plastic material behaviour. We present a viscoelastic-material model based on the model of two Kelvin–Voigt bodies in series. Contrary to the classical rheological model, we allow an interaction between the two Kelvin–Voigt bodies. Our model is able to reproduce the classic linear viscoelasticity and with including the interaction qualitatively capable of predicting material behaviour such as ratcheting. We underline this by providing qualitative numerical simulations for a one-dimensional rod stimulated by an asymmetric cyclic stress.
