Creep deformation and fracture tests on two polymeric materials were performed at various temperatures and strain rates. The data obtained were analyzed and used to test four viscoelastic fracture criteria, based on different theoretical approaches. No definitive conclusion could be reached as to the identification of an appropriate invariant fracture parameter.

Abstract
Creep deformation and fracture tests on two polymeric materials were performed at various temperatures and strain rates. The data obtained were analyzed and used to test four viscoelastic fracture criteria, based on different theoretical approaches. No definitive conclusion could be reached as to the identification of an appropriate invariant fracture parameter.File in questo prodotto:
