Inception of Strain Localization in Unsaturated Porous Media
The analytical solutions for the inception of strain localization in unsaturated elastic-plastic porous materials have been implemented into the constitutive driver for bounding surface plasticity model (Khalili et al., 2008). The solutions are based on the definition of effective stress proposed by Khalili and Khabbaz (1998), which is backed up by a substantial amount of experimental evidence. The strain localization behavior of unsaturated soils is further illustrated on the example of Bourke silt from Bourke region of New South Wales, Australia. To this end, the silt is subjected to three series of drained plane strain compression tests whereby the initial net mean stresses and suctions correspond to the range of initial overconsolidation ratios between 1.26 and 6.67. It is found that the axial strain at the inception of strain localization sharply decreases in a nonlinear fashion with the increasing overconsolidation ratio.
