It is well established that unreinforced masonry (URM) buildings develop damage-forming collapse mechanisms during high-intensity earthquakes, with these exhibiting large rocking displacements before collapsing. The Discrete Element Method (DEM) of analysis can realistically capture phenomena involve movements elements, resulting in the technique being ideal for simulating URM building elements...

The discrete element method (DEM) is becoming widely accepted as an effective for addressing tectonic problems in granular materials. It capable of reproducing structures observed the analog model (AM). However, previous experiments also pointed to variability among DEM models and AMs number fault zones, their dip angle spacing, evolution surface slope a thrust wedge. accuracy depends on input ...

Mesh convergence is a vital issue that needs to be addressed in numerical model. This study investigated the effects of mesh element number on Discrete Element Method (DEM) granite rock response under compression loading. used 3D finite-element code LS-DYNA model Unconfined Compression Test (UCT) simulation. Models with five different types were conducted for mesh, namely normal fine super coar...

One of the main goals of precision agriculture researches is to define a suitable decision support system (DSS) for farm management with the goal of optimizing returns on inputs while preserving resources. Therefore, our long-term objective is the development of an adequate DEM model which can be adapted in the actual decision support system (DSS) to create a new model driven decision support s...
