Nano-Composite Materials

The mechanical properties of nanocomposite materials made by mixing nanofillers into the amorphous structure of polyethylene were evaluated using Coarse-Grained Molecular Dynamics (CGMD). The effects of nanofiller size, shape, and surface characteristics on Young’s modulus and yield stress were evaluated.
Use Cases Highlights
  • Analysis of mechanisms for mechanical property improvement by nanofillers
  • Evaluation of the effect of surface properties
  • Evaluation of the relationship between intermolecular interactions and mechanical properties

Evaluation of stress–strain properties

Evaluation of stress–strain properties of polyethylene with nanofillers in glassy state is shown, indicating increased modulus and yield stress.
