在这方面的贡献，现象学材料建模的聚氨酯基粘合剂，包括固化过程被认为是。首先，考虑潜在的化学过程。为此，进行了差示扫描量热法实验，制定了反应热和所谓的固化度的模型，并确定了相应的模型参数。此外，在完全固化的材料上进行了循环加载的单轴拉伸试验，并揭示了弹性体的典型行为，如滞后、Mullins效应和永久变形。基于实验结果，本构模型已制定捕捉在完全固化状态下的材料的力学行为。最后，一种方法来捕捉固化过程中的机械行为的变化已经实现。（© 2017 Wiley‐VCH Verlag GmbH & Co. KGaA，魏因海姆）
In this contribution, the phenomenological material modelling of a polyurethane based adhesive including the curing process is considered. First, the underlying chemical process is regarded. To this end, differential scanning calorimetry experiments were carried out, models for the reaction heat and a so called degree of cure were formulated, and the corresponding model parameters were identified. Moreover, uniaxial tension tests with cyclic loading scenarios on the fully cured material were conducted and revealed typical behaviour of elastomers, like hysteresis, Mullins effect and permanent set. Based on the experimental results, a constitutive model has been formulated to capture the mechanical behaviour of the material in the fully cured state. Finally, an approach to capture changes of the mechanical behaviour during the curing process has been realized. (© 2017 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
