In the present work, the magneto-mechanical coupling in magneto-active elastomers is investigated from two different modeling perspectives: a micro-continuum and a particle-interaction approach. Since both strategies differ significantly in their basic assumptions and the resolution of the problem under investigation, they are introduced in a concise manner and their capabilities are illustrated by means of representative examples. To motivate the application of these strategies within a hybrid multiscale framework for magneto-active elastomers, their interchangeability is then examined in a systematic comparison of the model predictions with regard to the magneto-deformation of chain-like helical structures in an elastomer surrounding. The presented results show a remarkable agreement of both modeling approaches and help to provide an improved understanding of the interactions in magneto-active elastomers with chain-like microstructures.
在本工作中，从两个不同的建模角度研究了磁活性弹性体中的磁-机械耦合：微观连续体方法和粒子相互作用方法。由于这两种策略在其基本假设和所研究问题的解决方式上有显著差异，因此以简洁的方式进行了介绍，并通过代表性示例说明了它们的能力。为了推动这些策略在磁活性弹性体混合多尺度框架中的应用，随后在对围绕弹性体的链状螺旋结构的磁致变形的模型预测进行系统比较时，检验了它们的互换性。所呈现的结果表明两种建模方法具有显著的一致性，有助于更好地理解具有链状微观结构的磁活性弹性体中的相互作用。
