  • Published 2015


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 up to the peak load and well into the softening regime. We use a new micropolar hypoplastic framework to capture the development and propagation of a persistent… (More)
