Determining of mechanical properties of anisotropic hyperelastic materials is one of preliminary steps ofstudying these materials. In this work some models of anisotropic hyperelastic materials, for a coated fabric, have been analyzed and compared. The major differences between these models have also been emphasized, based onexperimental data of tension test in different directions. It is shown that from these models, a simplified Kaliske model agrees well in its predictions of mechanical behavior of this special coated fabric.
