Off-fault deformation feedback and strain localization precursor during laboratory earthquakes. [PDF]
Commun Earth EnvironRecent large-scale seismological observations have shown that off-fault strain localization and foreshock migration could serve as an early warning of an impending earthquake. However, this process is still largely unknown.

Spatial discretization of strain localization
, 1994 In recent years novel finite element techniques have been developed for capturing strain localization. Thier objective is to minimize mesh sensitivity of numerical solutions in the presence of destabilizing material effects due to stiffness degradation, strength softening and loss of associativity.

Strain localization analysis using a multiscale model [PDF]
, 2007 In order to analyze the formability of steels in sheet metal forming, a ductility loss criterion is coupled with a multiscale model. The behavior at the mesoscopic (grain) scale is modeled by a large strain micromechanical constitutive law, which is then

Disorder is good for you: the influence of local disorder on strain localization and ductility of strain softening materials [PDF]
International Journal of Fracture, 2017 We formulate a generic concept model for the deformation of a locally disordered, macroscopically homogeneous material which undergoes irreversible strain softening during plastic deformation. We investigate the influence of the degree of microstructural heterogeneity and disorder on the concomitant strain localization process (formation of a ...
