Abstract: Abstract Numerical methods for predicting localized shear failure in elasto-plastic solids have experienced considerable advancements in the last decades. Among these approaches, the so-called “Embedded Strong Discontinuity (ESD)” method is often successfully used to accurately… read more here.

DOI: 10.1016/j.pmatsci.2020.100755
Abstract: Abstract Three factors govern adiabatic shear localization: strain hardening (or softening), strain-rate hardening, and thermal softening. It is typically associated with large shear strains (>1), high strain rates (103-107 s-1), and high temperatures (40-100% of… read more here.

DOI: 10.1016/s1003-6326(21)65604-2
Abstract: Abstract The microstructure characteristics in early stage shear localization of near-α Ti−6Al−2Zr−1Mo−1V titanium alloy were investigated by split Hopkinson pressure bar (SHPB) tests using hat-shaped specimens. The microstructural evolution and deformation mechanisms of hat-shaped specimens… read more here.
