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...
Critical state plasticity. Part VI:Meso-scale finite element simulation of strain localization in discrete granular materials
Granular materials Strain localization
2015/7/1
Development of more accurate mathematical models of discrete granular material behavior requires a fundamental understanding of deformation and strain localization phenomena. This paper utilizes a mes...
