Mooney Rivlin Hyperelastic material failure

Mooney Rivlin Hyperelastic material failure

(OP)
Hi, all. I have defined a mooney rivlin material in abaqus, with a predefined set of points to elongation at break. However, I experience the material to take up more stress than what the material is capable of, based on a uniaxial stress strain curve. The stress state is triaxial, although the analysis is 2d axixymmetric. How can this be, and what is the failure mode?
