A lattice discrete element method to model the falling-weight impact test of PMMA specimens
(Elsevier, 2016-01)
It is introduced in this paper a Lattice Discrete Element Method (LDEM) for modelling the falling-
weight test of polymethyl-methacrylate (PMMA) specimens. The method exploits the inherent characteristics
of discrete ...
Model for vickers microhardness prediction applied to SnO2 and TiO2 in the normal and high pressure phases
(Elsevier, 2014-06-14)
The Vickers microhardness of TiO2 is calculated using elastic properties obtained by first principles calculations combined with Discrete Elements
Method (DEM). The calculation is carried out in rutile and cotunnite phases. ...
