Mesoscopic Distinct Element Method for Multiscale Modeling of Carbon Nanotubes
… CNT assembles with all atom simulation methods, but this approach is computationally prohibitive. Due to the inherent spatial and temporal limitations of atomistic modeling and the lack of mesoscale models, mesoscopic simulation methods for CNT systems are missing. My work focuses on …

Study of fault gouge influences on mechanical and frictional behavior of granular shear zones using the distinct element method
… in "real time", the combination of the Distinct Element Method (DEM) and linear elastic contact bonds provides an opportunity to deform complex, heterogeneous granular assemblages that approximate natural shear zones in a more realistic way, and to study gouge deformation processes that …

Distinct Element Simulation of the February 17th, 2006, Leyte, Philippines Rockslide
… 1,400 of the 1,800 residents of the village. The distinct element simulation of the rockslide is performed using 3DEC (Three-Dimensional Distinct Element Code) in order to investigate the underlying triggering mechanism of the slide as well as the behavior of the debris flow. The 3DEC models were …

Dynamic simulation of particulate and molecular systems
… bimodal and Gaussian) are studied using the Distinct Element Method (DEM). The dissipative forces including viscoelastic and frictional contact forces between the colliding particles cause the energy loss during the packing process, and finally the particles agglomerations is formed. When the …

Evaluation and Assessment of Inflow Rates in Tunnels Excavated in Jointed Rock Mass
… groundwater inflows were investigated using 2-D Distinct Element Method Program which can take into account the coupled hydro-mechanical behavior within the rock fractures. The main concluding points of the study can be summarized as follows: (1) The hydro-mechanical behavior of the ring of …

Risposta sismica fuori piano di strutture murarie: gli effetti P-Delta in un approccio a macro-elementi
… presente lavoro presenta un’evoluzione the macro-elemento discrete che tiene conto degli effetti del secondo ordine (cosiddetti effetti P-Delta P-Δ) in grado di descriver la risposta di rocking di muri in muratura soggetti a carichi fuori dal proprio piano. In accordo con la strategia a …
