A comprehensive experimental study performed under a combination of thermo-electro-mechanical loads applied to a widely used electro-active polymer, is presented in the Part I of this work (Mehnert et al., 2021). Soft polymeric materials, used as base materials in electro-active polymers, are highly susceptible to temperature changes. Hence, thermal influences on their behavior have to be investigated precisely. Constitutive modeling and numerical simulation of electro-active polymers are active fields of current research. However, on the one hand, their experimental study under complex loading conditions is non-trivial. On the other hand, very few constitutive modeling approaches meet with experimental data obtained from thermo-electro-mechanical loading conditions. In this contribution, we aim to develop a thermo-electro-mechanically coupled model, which will closely replicate the response of an electro-active polymer investigated under a combination of thermal, electric and mechanical loads. Once the model is calibrated with the experimental data described in Part I of this contribution, it is validated with a different set of data, which shows excellent agreement with experimental findings.

本工作的第一部分介绍了在应用到广泛使用的电活性聚合物的热机电负载组合下进行的综合实验研究（Mehnert 等人，2021 年）。用作电活性聚合物基础材料的软聚合物材料对温度变化非常敏感。因此，必须精确研究热对其行为的影响。电活性聚合物的本构建模和数值模拟是当前研究的活跃领域。然而，一方面，他们在复杂负载条件下的实验研究是不平凡的。另一方面，很少有本构建模方法符合从热机电负载条件获得的实验数据。在这个贡献中，我们的目标是开发一种热机电耦合模型，该模型将密切复制在热、电和机械负载组合下研究的电活性聚合物的响应。一旦使用本贡献的第 I 部分中描述的实验数据校准模型，就会使用不同的数据集对其进行验证，这表明与实验结果非常吻合。
