A treatment of multiscale quasistatic processes that combines an atomistic description of microscopic heterogeneous ("near") regions of a material with a coarse-grained (quasicontinuum) description...
Zhou, H., Feng, Ruqiang, Diestler, Dennis J., Zeng, Xiao Cheng
A new treatment of quasistatic (reversible) multiscale processes in heterogeneous materials at nonzero temperature is presented. The system is coarse grained by means of a finite-element mesh. The...
Hybrid atomistic-coarse-grained treatment of thin-film lubrication. I (2004)
Wu, Z.-B., Diestler, Dennis J., Feng, Ruqiang, Zeng, Xiao Cheng
A technique that melds an atomistic description of the interfacial region with a coarse-grained description of the far regions of the solid substrates is presented and applied to a two-dimensional...
Dzenis, Youris A, Feng, Ruqiang, Larsen, Gustavo, Turner, Joseph, Zeng, Xiao
This project is in the area of nanomanufacturing of advanced nanostructured materials. Nanostructured materials (NSMs) with unusual and extreme properties will play a key role in many emerging...
Coarse-graining description of solid systems at nonzero temperature (2003)
Wu, Z.-B., Diestler, Dennis J., Feng, Ruqiang, Zeng, Xiao Cheng
The quasicontinuum (QC) technique, in which the atomic lattice of a solid is coarse-grained by overlaying it with a finite-element mesh, has been employed previously to treat the quasistatic...
