Abstract
A cavitation criterion defines a failure surface in three-dimensional stress space, which represents the onset of excessive void growth and therefore the strong degradation of the bulk modulus considering rubber-like materials [2, 3]. The damaging effect of cavitation was analyzed experimentally by Busse [1], Yerzley [9] and later Gent & Lindley [5]. In the pioneering work of Gent & Lindley [5], two flat cylinders vulcanized with thin sheets of natural rubber were tested in axial tension.
