As thermoset polymers find frequent implementation in engineering design, their application in structural engineering is rather limited. One key reason relies on the ongoing curing process in typical applications such as post-installed adhesive anchors, joints by structural elements or surface-mounted laminates glued by adhesive polymers. Mechanochemistry including curing and aging under thermal as well as mechanical loading causes a multiphysics problem to be discussed. For restricting the variety of material models based on empirical observations, we aim at a thermodynamically sound strategy for modeling thermosets. By providing a careful analysis and clearly identifying the assumptions and simplifications, we present the general framework for modeling and computational implementation of thermo-mechano-chemical processes by using open-source codes.

由于热固性聚合物在工程设计中频繁使用，其在结构工程中的应用相当有限。一个关键原因依赖于典型应用中持续的固化过程，例如后安装的粘合锚栓、结构元件的接头或由粘合剂聚合物粘合的表面安装层压板。机械化学，包括热和机械载荷下的固化和老化，引起了需要讨论的多物理问题。为了限制基于经验观察的材料模型的多样性，我们的目标是采用热力学合理的策略来模拟热固性材料。通过仔细分析并清楚地确定假设和简化，我们提出了使用开源代码对热机械化学过程进行建模和计算实现的通用框架。
