本文介绍了不可压缩的炭黑填充弹性体的特性，作为高度填充橡胶的一个典型例子。它显示出非常明显的非线性粘弹性行为，最重要的特征是必须考虑的极长松弛时间。材料模型是相对于单轴拉伸数据。唯象模型发展的基础是基本弹性力学。对于该评估，长期弛豫行为导致复杂的实验程序。因此，必须特别注意根据优化的实验过程，以便以充分和可重复的方式获得必要的参考数据[1]。在此模型基础上，考虑了与时间相关的粘弹性的进一步研究。因此，从零到最大变形的循环变形被认为是不同的应变率。此外，松弛行为进行了研究多个应变水平。在实验结果中观察到的现象产生于纯粘弹性模型，该模型基于流变学类似模型，该流变学类似模型由平衡弹簧和几个麦克斯韦单元组成，其中包含阻尼器单元松弛时间的非线性关系[1，2]。材料模型的数值实现通过两种方式实现。由于其数值计算简单，特别是根据参数识别，该模型仅限于单轴拉伸的简单情况。执行第二替代实施方案，其提供还可考虑更复杂的变形条件的益处。因此，通用三维有限元模型在开源有限元库中实现[3]。（© 2015 Wiley‐VCH Verlag GmbH & Co.

This contribution presents the characterisation of an incompressible carbon black‐filled elastomer as one characteristical example for highly filled rubber. It shows a strongly pronounced non‐linear viscoelastic behaviour and the most important characteristic is the extremely long relaxation time which has to be taken into account. The material model is developed with respect to uniaxial tension data. The basis in the development of a phenomenological model is given by the basic elasticity. For this evaluation the long term relaxation behaviour results in a complex experimental procedure. Therefore, special attention has to be paid according to an optimised experimental process in order to get the necessary reference data in an adequate and reproduceable way [1].With this model basis further investigations are taken into account concerning the time‐dependent viscoelasticity. Therefore, cyclic deformations from zero up to a maximum of deformation are considered for different strain rates. Furthermore, the relaxation behaviour is investigated for multiple strain levels. The phenomena which are observed in the experimental results yield in a purely viscoelastic model, based on a rheological analogous model consisting of an equilibrium spring and several Maxwell‐elements which contain nonlinear relations for the relaxation times of the dashpot elements [1,2].The material model's numerical realisation is accomplished in two ways. Because of its numerical simplicity especially according to the parameter identification the model is restricted only to the simple case of uniaxial tension. A second, alternative implementation is executed providing the benefit that more complex deformation conditions can also be taken into account. Therefore, the general, three‐dimensional finite model is implemented in an open‐source Finite Element library [3]. (© 2015 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
