A Visco-Elastic DEM Model of Rock Under Different Loading Rates

2021
A numerical model based on two-dimensional Discrete Element Method (DEM) has been used to study the compression of rock under different loading rates, and a visco-elastic Flat-Joint constitutive law has been developed to describe the dynamic behavior of bonded contact between particles.

DEM analysis of compression breakage of 3D printed agglomerates with different structures

Powder Technology, 2019
Abstract Understanding agglomerate breakage characteristics is of great importance in industries of particulate manufacturing. In this work, Discrete Element Method (DEM) combined with Timoshenko Beam Bond Model (TBBM) is employed to simulate the agglomerate breakage with different structures subject to compressive loads. The agglomerates are made of

Landslide monitoring: use of multi-temporal DEMs derived from different techniques [PDF]

, 2004
The comparison of Digital Elevation Models (DEMs) is a powerful tool for Earth surface deformation studies in landslide area. The use of DEMs allows in many cases a full description of the process, while the classical geodetic ground-based measurements give a sampling of deformation field at a limited number of points.

Uncertainty of SWAT model at different DEM resolutions in a large mountainous watershed

Water Research, 2014
The objective of this study was to enhance understanding of the sensitivity of the SWAT model to the resolutions of Digital Elevation Models (DEMs) based on the analysis of multiple evaluation indicators. The Xiangxi River, a large tributary of Three Gorges Reservoir in China, was selected as the study area.

Comparison of Various DEMs for Height Accuracy Assessment Over Different Terrains of India

IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019
In this paper, the height accuracy of various DEMs such as TanDEM-X Global DEM, newly released TanDEM-X 90 m DEM, TanDEM-X ascending or descending DEM, SRTM 30 m, 90 m DEMs, provisional version of the NASADEM, and the aerial LiDAR DEM are assessed over three different Indian terrains.

Evaluating Information Loss of SRTM DEM Data with Different Grid Sizes

Journal of Surveying Engineering, 2014
AbstractThe digital elevation products produced by the Shuttle Radar Topography Mission (SRTM) are disseminated with different resolutions. This study investigates the differences in information content between different resolutions. Three 1° cells are selected to represent flat area, moderate terrain, and mountain ranges.
