Influence of nanoparticulate agglomeration on load transfer characteristics of polymer nanocomposites: a multiscale study

초록

The theoretical understanding of load transfer characteristics weakened by nanoparticulate agglomeration remains insufficient. In this study, the weakening of load transfer characteristics of the polymer nanocomposites due to the nanoparticulate agglomeration phenomenon is investigated using a multiscale modeling approach, combining the molecular dynamics (MD) simulation with the finite element-based homogenization method. Specifically, to effectively describe the elasto-plastic behavior and load transfer characteristics of the polymer nanocomposites, a multiscale approach is proposed. The mechanical behaviors obtained from the proposed multiscale approach exhibit good consistency with those obtained from the MD simulations. These results indicate that the proposed multiscale approach can effectively describe the weakening of the load transfer characteristics of the polymer nanocomposites due to the nanoparticulate agglomeration.
