The Rubber Cord Adhesion Inflation Test (RCAIT) is a recently proposed test protocol to study tyre rubber-steel cord fracture (Kane et al., 2019). As in the traditional blister test, a pressurised fluid is injected between the two adherends to propagate fracture. The fracture energy, G_c, is directly related to the strain energy stored in the inflated rubber. It was shown that evaluation of G_c for RCAIT depends intimately on how well the hyperelastic model is capable of predicting the rubber inflation condition (Kane et al., 2020). Here, a thick tube inflation model is proposed for a generalised, phenomenological, hyperelastic material. It is subsequently applied to RCAIT in order to study which data processing technique is likely to be the most reliable to evaluate the critical strain energy release rate of the specimen.

橡胶帘线粘合性充气测试（RCAIT）是最近提出的用于研究轮胎橡胶-钢丝帘线断裂的测试方案（Kane等，2019）。与传统的起泡测试一样，在两个被粘物之间注入加压流体以扩展断裂。断裂能，G ^ _{C ^，}直接关系到存储在所述充气橡胶的应变能量。结果表明，对G _c的评估RCAIT的精确性直接取决于超弹性模型能否很好地预测橡胶的充气状况（Kane等，2020）。在此，为广义的现象学超弹性材料提出了粗管膨胀模型。随后将其应用于RCAIT，以研究哪种数据处理技术可能最可靠地评估样品的临界应变能释放速率。
