Identification of anisotropic properties of polymer sheets from heterogeneous biaxial tests

The stretch blowing process for PET bottle induces the anisotropic mechanical properties due to the different elongation of macromolecular chains. For example, the Young's modulus can be multiplied by almost two in the longitudinal direction and more than 3 times in the hoop direction of the pl...
