Abstract: Abstract Isotropic compression and drained axisymmetric triaxial compression tests were performed on six structural backfill aggregates commonly used in the construction of geosynthetic-reinforced soil (GRS) systems to characterize their shear behavior. The behavior of these… read more here.

DOI: 10.1190/int-2018-0143.1
Abstract: Brittleness is an important evaluation parameter in shale fracturing. Current methods of brittleness evaluation can be classified into two categories: elastic parameter-based and mineral content-based methods. However, both categories neglect the effect of anisotropy on… read more here.
