Studies of spatial variability and simulation of available soil water and extractable soil water are scarce and yet such data are essential in hydrologic and solute transport modeling. A study was con...
Capturing strain localization behind a geosynthetic-reinforced soil wall
constitutive relations deformation earth pressures failure geosynthetics numerical modelling plasticity retaining walls strain localization
2015/7/1
This paper presents the results of finite element (FE) analyses of shear strain localization that occurred in cohesionless soils supported by a geosynthetic-reinforced retaining wall. The innovative a...
Geologic time is shorthand for slow-paced. But new measurements from steep mountaintops in New Zealand shows that rock can transform into soil more than twice as fast as previously believed possible.
