Run-out of landslides in brittle soils [PDF]
, 2016 One of the factors causing the acceleration of landslides is the loss of strength of the soil involved in the potential unstable mechanism. The travelled distance and the landslide velocity, a key factor in risk analysis, will be determined by the loss ...

Brittleness Evaluation in Shale Gas Reservoirs and Its Influence on Fracability
Energies, 2020 The brittleness index (BI) is a key parameter used to identify the desirable fracturing intervals of shale gas reservoirs. Its correlation with fracability is still controversial. There have been a variety of methods proposed that can estimate BI.

Fracture of Brittle Metallic Glasses: Brittleness or Plasticity
Physical Review Letters, 2005 We report a brittle Mg-based bulk metallic glass which approaches the ideal brittle behavior. However, a dimple structure is observed at the fracture surface by high resolution scanning electron microscopy, indicating some type of "ductile" fracture mechanism in this very brittle glass. We also show, from the available data, a clear correlation between
