The recent focus of the scientific community on multiscale computer modeling techniques of
nano-engineered materials stems from the desire to develop more realistic methodologies …

Rock is geometrically and mechanically multiscale in nature, and the traditional
phenomenological laws at the macroscale cannot render a quantitative relationship …

The equation of state (EOS) plays an important role in high-velocity impact process since
phase transformation, melting, and even vaporization may happen under such extreme …

The material properties of aluminum foam are investigated numerically with point-based
microstructure models. The models are reconstructed conveniently from microstructure …

Material point method (MPM) discretizes the material domain by particles, and solves the
momentum equations on a predefined background mesh. MPM avoids mesh entanglement …

A point-based modeling scheme for the meso-structure of the 3D orthogonal woven
composite is developed. Different from the traditional mesh-based modeling scheme, more …

A concurrent multiscale method coupling molecular dynamics (MD) and continuum‐based
material point method (MPM) is proposed. Seamless coupling is realized by utilizing …

Atomic size differences between constituting elements and the heat of mixing are key factors
in designing a metallic glass system. In this study, the effects of atomic size differences and …

A predictive constitutive model for single-crystal β-octahydro-1, 3, 5, 7-tetranitro-1, 3, 5, 7-
tetrazocine (β-HMX) under simple loading conditions was developed using a hierarchical …
