TBPLaS 2.0: a Tight-Binding Package for Large-scale Simulation
Yunhai Li, Zewen Wu, Miao Zhang +2
The common exact diagonalization-based techniques to solving tight-binding models suffer from O(N^2) and O(N^3) scaling with respect to model size in memory and CPU time, hindering…

Elasto-plastic cell-based smoothed finite element method solving geotechnical problems
Yang Yang, Mingjiao Yan, Zongliang Zhang +4
This work develops an elasto-plastic cell-based smoothed finite element method (CSFEM) for geotechnical analysis. The formulation incorporates a smoothed strain field into the stan…
