Résumé en anglais

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, Gc, is directly related to the strain energy stored in the inflated rubber. It was shown that evaluation of Gc 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.< Réduire
