Critical state plasticity. Part VII: Triggering a shear band in variably saturated porous media
Bifurcation Critical state theory Heterogeneity Mixed formulation Shear band Unsaturated porous media
2015/7/1
In a previous paper (Part VI), the impact of spatially varying density on the localization of deformation of granular materials has been quantified using mesoscopic representations of stresses and def...
Micropolar hypoplasticity for persistent shear band in heterogeneous granular materials
Finite elements Heterogeneity Hypoplasticity Micropolar theory Persistent shear band
2015/7/1
Persistent shear bands in heterogeneous materials develop progressively, rather than instantaneously. For a meaningful capture of this deformation pattern, the band must develop naturally and freely u...
Bifurcation of elastoplastic solids to shear band mode at finite strain
Bifurcation Elastoplastic solids Shear bond mode Finite strain
2015/7/1
This paper formulates and implements a finite deformation theory of bifurcation of elastoplastic solids to planar bands within the framework of multiplicative plasticity. Conditions for the onset of s...
