A constitutive model for large multiaxial deformations of solid polypropylene at high temperature

Experiments on a blow‐molding grade of polypropylene have been performed at 135°C using a biaxial testing machine. Both simultaneous and sequential equibiaxial tests were performed at strain rates relevant to solid phase processing regimes. A constitutive model has been developed that includes a sin...
