Title: A multiscale study on the interfacial behavior of polymer nanocomposites with inelastic behavior
Abstract: In this study, a hierarchical multiscale modeling approach to characterize the elastoplastic behavior of polymer nanocomposites is proposed. Molecular dynamics simulation and a continuum nonlinear two-scale homogenization method are merged into the proposed multiscale modeling. The characterization of the condensed interphase zone between silica nanoparticle and polymer matrix are conducted. Nonlinear mechanical behavior of polymer nanocomposites was identified by molecular dynamics simulation. Uniaxial tensile simulations are employed through NPT ensemble simulation. Stress-strain relationship of Nylon6 is fitted by elastoplastic model in this study. The elastoplastic behavior of effective interphase is quantified by iterative inverse algorithm based on the nonlinear two-scale homogenization method.
