Fracture of model end-linked networks
Abstract
Fracture of polymer networks is molecular in nature as chains must rupture for a crack to propagate. Predicting macroscopically measured fracture properties from molecular parameters a priori has remained elusive, even for well-defined networks. This work shows that a newly developed theory, which accounts for network defects, quantitatively describes both experimental measurements and molecular dynamics (MD) simulation data for fracture of a polymer network with independently defined or measured parameters. This advance provides a missing link between chemistry and materials science and engineering for polymer networks.
