Hi All,

I am modelling rubber using Abaqus. According to Abaqus theory manual The Ogden model at N=2 and N=3 fits the rubber test data very accurately for all three modes of deformation. However it is unstable for my uniaxial test data (attached). Has this happened to anyone else before?

Thanks,
Gazo
