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

Hierarchical {332}<113> twinning in a metastable β Ti-alloy showing tolerance to strain localization
, 2020 A hierarchical {332} twinning system is studied in a metastable beta Ti-12Mo-10Zr (wt%) alloy, which shows strong twinning-induced plasticity (TWIP) effect due to a three-level twinning mechanism.

Fracture of disordered solids in compression as a critical phenomenon: III. Analysis of the localization transition [PDF]
, 2002 The properties of the Hamiltonian developed in Paper II are studied showing that at a particular strain level a ``localization'' phase transition occurs characterized by the emergence of conjugate bands of coherently oriented cracks.

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 ...
