摘要：

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.
