在作为介电弹性体的代表的颗粒填充的硅树脂上在机电载荷的组合下进行的综合实验研究在本工作的第I部分中呈现（Mehnert等人，2021年）。电活性聚合物的本构建模和数值模拟是重要的研究领域，以提高这组软智能材料在现实生活中的应用。然而，只有少数的贡献，包含本构建模方法相结合的实验数据从机电耦合加载条件下，由于相应的实验的复杂性。在这方面的贡献，我们的目标是开发一个机电耦合模型，它密切复制的有机硅聚合物填充有不同分数的高介电常数填料的响应，其特征在于在电气和机械负载的组合。一旦该模型是校准与本贡献的第一部分中描述的实验数据，它是用于一个简单的说明性的应用程序的例子，展示了该模型的能力和不同的材料特性的影响。
A comprehensive experimental study performed under a combination of electro-mechanical loads on a particle-filled silicone as a representative of dielectric elastomers is presented in the Part I of this work (Mehnert et al., submitted, 2021). The constitutive modeling and numerical simulation of electro-active polymers are essential fields of research in order to increase the acceptance of this group of soft smart materials in real-life applications. However, only few contributions containing constitutive modeling approaches are combined with experimental data obtained from electro-mechanically coupled loading conditions due to the complexity of corresponding experiments. In this contribution, we aim to develop an electro-mechanically coupled model, which closely replicates the response of a silicone polymer filled with a high dielectric permittivity filler of varying fractions that are characterized under a combination of electric and mechanical loads. Once the model is calibrated with the experimental data described in Part I of this contribution, it is used for a simple illustrative application example showcasing the capability of the model and the influence of the different material characteristics.
