Watch the video at around 3:10. If you only have Biaxial data, then material response in only that mode of deformation may be considered reliable. Material response in other modes may not be as reliable. So if your model deforms only in the biaxial load, this data set might be sufficient. But if it deforms in other modes, you need more data to caliberate your hyperelastic material model and to get sufficiently reliable results in your simulation.
