Modelling the brightness increase signature due to asteroid collisions

, 2015
We have developed a model to predict the post-collision brightness increase of sub-catastrophic collisions between asteroids and to evaluate the likelihood of a survey detecting these events.

Application of the FDEM Based on the CZM in Simulating Three-Point Bending Test of Frozen Soil

Atmosphere, 2022
The combined finite–discrete element method (FDEM) based on the cohesive zone model (the CZM) achieves cracking simulation by inserting cohesive elements between solid elements.

A micromechanical model of collapsing quicksand

, 2010
The discrete element method constitutes a general class of modeling techniques to simulate the microscopic behavior (i.e. at the particle scale) of granular/soil materials.

PENGARUH ANYAMAN BAMBU TERHADAP DAYA DUKUNG DAN PENURUNAN PONDASI DANGKAL PADA TANAH KOHESIF [PDF]

, 2007
The problems of construction on cohesive soil with high water content are low bearing capacity and high settlement. Usage of bamboo matting is expected to overcome these problems. This research is aimed at investigating the influences of bamboo matting

Anti‐Slip Material‐Based Strategies and Approaches

Advanced Materials Technologies, EarlyView.
This review highlights the principle mechanisms of slipping at the microscale, linking contact mechanics with a friction behavior model for surface interfaces. Main strategies to develop anti‐slip properties to the surfaces are discussed alongside standardized testing approaches.

Shear strength of geomembrane-cohesive soil interfaces [PDF]

E3S Web of Conferences
Despite the increasing use of geosynthetics, the behavior of polymeric materials inserted in the soil is complex, and the wide availability of products on the market makes it difficult to standardize and predict the behavior of the interaction. Therefore,

Wet Granular Materials

, 2006
Most studies on granular physics have focused on dry granular media, with no liquids between the grains. However, in geology and many real world applications (e.g., food processing, pharmaceuticals, ceramics, civil engineering, constructions, and many ...
