Shear deformation of model networks: A Monte-Carlo-Study — •Toni Müller1,2, Michael Lang1, and Jens-Uwe Sommer1,2 — 1Leibniz-Institut für Polymerforschung Dresden — 2Technische Universität Dresden
Using the bond-fluctuation model, we compare the elastic properties of end-linked model networks with model systems where either entanglements or both entanglements and excluded volume were switched off in the computer simulation. In our simulations we apply a shear-stress to the periodic simulation box and calculate the deformation in equilibrium. The goal of this study is to consider the contribution of connectivity and of topological constraints to the shear modulus separately. We expect further insight into the influence of network defects and the impact of excluded volume on the elasticity. As a result we can make an reasonable estimate for the entanglement degree of polymerization.
