Publication on interphase characterization in polymeric nanocomposites
We are delighted to announce the publication of “A coupled MD-FE methodology to characterize mechanical interphases in polymeric nanocomposites” in the International Journal of Mechanical Sciences.
We introduce an unconventional procedure to characterize spatial profiles of elastic and inelastic properties inside polymer interphases around nanoparticles. Instead of real experiments, we perform pseudo-experiments using our recently developed Capriccio method, which is an MD-FE domain-decomposition tool designed explicitly for amorphous polymers. These pseudo-experimental data then serve as input for a typical inverse parameter identification. With this procedure, spatially varying mechanical properties inside the polymer are, for the first time, translated into intuitively understandable profiles of continuum mechanical parameters. https://doi.org/10.1016/j.ijmecsci.2021.106564
