The mechanical properties of nano-structured materials are important field of exploration in the fields of materials science and other engineering disciplines. Thorough understanding of underlying material structure and resulting properties require a

Nanoindentation is an effective approach for measuring mechanical properties of nanoscale films coated on substrates, yet results obtained through the classic Oliver–Pharr model require additional consideration due to the existence of a “substrat

Molecular dynamics and molecular mechanics simulations are used to establish well-equilibrated, validated molecular models of the EPON 862-DETDA epoxy system with a range of crosslink densities using a united atom force field. Molecular dynamics simu

A large number of possible polymer chain conformations exist for a given volume of an amorphous polymer. The prediction of elastic properties of a polymer must therefore consider more than a single combination of chain conformations. A multiscale mod

Several recent studies have reported that the elastic strain in metallic glasses, as measured from peak shifts in the pair-correlation functions of samples under load, increases with distance from an average atom, approaching the macroscopic strain a

Molecular dynamics simulations of cavitation in a ${\mathrm{Zr}}_{50}{\mathrm{Cu}}_{50}$ metallic glass exhibit a waiting time dependent cavitation rate. On short time scales nucleation rates and critical cavity sizes are commensurate with a classica

Molecular Dynamics simulations are used to study cross-linking of an epoxy polymer. OPLS force field parameters are used for modeling a 2:1 stoichiometric mixture of epoxy resin and the cross-linking agent. The model has 17,928 united atoms and a sta

A series of molecular models have been developed to predict the bulk elastic properties of polyimide and polycarbonate polymer systems. Specifically, the two polymer systems have been modeled for a range of polymer chain lengths to predict the influe

First-principles density-functional calculations of the electronic structure, energy band gaps $({E}_{g})$, and strain-induced band gap changes in moderate-gap single-walled $(n,0)$ carbon nanotubes (SWNTs) are presented. It is confirmed that $(n,0)$
