Triggering a Shear Band in Variably Saturated Porous Materials
We investigate the effect of spatially varying density and degree of saturation on the triggering of a persistent shear band in unsaturated porous materials. Recent papers (Borja et al. 2013a, 2013b) have shown that these two types of heterogeneity can have first-order effects on the ensuing shear band. Advances in non-invasive testing have now allowed accurate measurement and quantification of density and degree of saturation variations in granular materials; hence, these two types of heterogeneity can now be input deterministically into a hydromechanical model for more realistic modeling and simulation. We show a representative numerical simulation illustrating the triggering of a persistent shear band in soils with spatially varying density and degree of saturation.
