Abstract Scope |
This paper aims to provide the microstructure evolution for high-strain rate mechanical response for two epoxy combinations of diethylenetriamine (DETA) and isophorone diamine (IPD) to a resin of diglycidyl ether of bisphenol-A (DGEBA). Molecular dynamics (MD) studies provide the ability to capture the dynamic deformation response of the crosslinked epoxy resin networks at the atomic scales. The interatomic interactions in the DGEBA/IPD and DGEBA/DETA systems are defined using the polymer consistent force field (PCFF) and the reactive force field (ReaxFF). The MD simulations investigate the deformation and failure response under high rate loading conditions of uniaxial strain compression and tension, as well as under shock loading, in addition to modifications including water absorption. The atomic level insights provided can help to provide a better understanding of the dynamic deformation and failure mechanisms in epoxy resins, to aid in the design of moisture prevalent environments. |
