Due to their typical material characteristics, elastomer components are used in almost all areas of engineering. In many cases, these components are subject to large cyclic deformations which result in hysteresis and dissipation-induced self-heating. Further they are exposed to varying ambient temperatures. Increased component temperatures can lead to the loss of a function or to total failure. Therefore, it is important to understand the causes and influences of critical temperatures and to identify them early in the development process under the condition of efficient applicability. In addition to the calculation time and accuracy, this also includes the experimental effort required to identify the material parameters and perform validation measurements. Within this work, the phenomenon of dissipative heating in elastomers is investigated in a numerical study using a modified model of the finite thermoviscoelasticity. For this purpose, a sufficiently simple material model was formulated and implemented under the assumption of the quasi-incompressible material behaviour. Based on this, the type and the characteristic features of the self-heating effect are specifically considered, and its dependence on thermal and mechanical initial and boundary conditions is studied. Thus, a new suitable parameter is introduced, which is particularly useful to identify critical loads. Analogously, the identification of dissipation-sensitive temperature ranges is presented. The utility of the general steadystate equilibrium condition as initial condition is also shown. Furthermore, the influence of the material properties on the steadystate equilibrium is demonstrated for the first time through parameter studies. Based on these findings, recommendations for modelling, calculation and experimental parameterisation are proposed.

由于其典型的材料特性，弹性体组件几乎用于所有工程领域。在许多情况下，这些组件会经历较大的周期性变形，从而导致磁滞和耗散引起的自热。此外，它们暴露于变化的环境温度。升高的组件温度可能导致功能丧失或完全故障。因此，重要的是要了解临界温度的原因和影响，并在有效应用的条件下及早在开发过程中找出临界温度。除了计算时间和准确性外，这还包括确定材料参数和执行验证测量所需的实验工作。在这项工作中，在数值研究中，使用有限热粘弹性的改进模型对弹性体中的耗散加热现象进行了研究。为此，在准不可压缩材料行为的假设下，制定并实施了一个足够简单的材料模型。在此基础上，具体考虑了自热效应的类型和特征，并研究了其对热，机械初始和边界条件的依赖性。因此，引入了新的合适参数，这对于识别关键负载特别有用。类似地，给出了对耗散敏感的温度范围的识别。还显示了一般稳态平衡条件作为初始条件的效用。此外，通过参数研究首次证明了材料性能对稳态平衡的影响。基于这些发现，提出了有关建模，计算和实验参数化的建议。
