Abstract

Abstract: A novel test configuration is proposed to characterize the adhesion between an elastomeric matrix and an included steel cord. The circular cylindrical, rubber envelope is bonded to the cord along the axis of symmetry. A crack is forced to propagate along the interface by inflating the rubber envelope using a pressurised liquid in between the two media. The constant pressure recorded during the test is used to evaluate the interfacial critical strain energy release rate (Critical SERR). This is achieved using an analytical model, taking into account both the incompressible, hyperelastic nature of the rubber and geometrical nonlinearity due to large deformations. An energy balance is proposed to evaluate the interfacial SERR.
