title: Mechanical testing of glassy and rubbery polymers in numerical simulations: role of boundary conditions in tensile stress experiments.
abstract: We use coarse-grained molecular dynamics simulations to perform tensile test deformation on glassy and rubbery polymer samples using two types of driving for the deformation. We compare the outcome from a standard homogeneous deformation procedure with that of a boundary driven procedure in which the sample is driven by the nanometric equivalent of grips. No significant difference is observed in both uniaxial and triaxial tensile experiments. Implications for testing the behavior of nonhomogeneous polymer materials are briefly discussed.
