Epoxy resins are widely used in advanced materials due to their exceptional mechanical properties. Among them, Epon 862/DETDA is a commonly employed thermoset system in aerospace and automotive applications. This study employs molecular dynamics simulations to investigate the mechanical behavior of the Epon 862/DETDA epoxy network. The simulations were conducted using cross-linked molecular models to represent the cured network, incorporating detailed atomic scale interactions. Mechanical behavior was evaluated by simulating stress-strain responses under tensile loading conditions and shear test for the elasticity tensor, revealing the epoxy networks high modulus and strength. Additionally, the study examines the effects of varying cross-link densities and molecular configurations on the materials performance.
