Abstract
Dynamic tension and Taylor impact experiments were
performed to study the high-rate inhomogeneous deformations in polymers
under a range of conditions. The mechanics of deformation were examined
utilizing finite element simulations together with a physically based
constitutive model of large-strain high-rate deformation behaviour of
polymers. The comparison of the numerical predictions with the high-speed
photographic data and final deformed shapes demonstrates the effectiveness
of the constitutive model in predicting the progression of complex
inhomogeneous deformation events during impact loading scenarios.
