Role of Nanoscale Cross-Link Heterogeneity in Epoxy Fracture: Insights from Molecular Dynamics Simulations
Fully atomistic reactive molecular dynamics simulations were used to investigate how nanoscale cross-link heterogeneity affects the mechanical response and fracture behavior of DGEBA/33DDS epoxy networks. Epoxy models containing controlled low-cross-link regions were subjected to dynamic and quasi-static tensile defo...
