Generalized cavitation criterion for poro-hyperelastic materials
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 , Yerzley  and later Gent & Lindley . In the pioneering work of Gent & Lindley , two flat cylinders vulcanized with thin sheets of natural rubber were tested in axial tension.
