Heterogeneous solute segregation suppresses strain localization in nanocrystalline Ag-Ni alloys
, 2020 Solute segregation to individual grain boundaries is used by design to produce strong and stable nanocrystalline metallic alloys. Grain-boundary segregation, however, is known to cause adverse embrittlement effects from a strain-localization failure ...

Loss of PopZ At activity in Agrobacterium tumefaciens by Deletion or Depletion Leads to Multiple Growth Poles, Minicells, and Growth Defects. [PDF]
, 2017 Agrobacterium tumefaciens grows by addition of peptidoglycan (PG) at one pole of the bacterium. During the cell cycle, the cell needs to maintain two different developmental programs, one at the growth pole and another at the inert old pole.

Finite element simulation of strain localization in inelastic solids by energy relaxation
Vietnam Journal of Mechanics, 2011 A new approach for the treatment of strain localization in inelastic material is proposed. It is based on energy minimization principles associated with micro-structure developments. Shear bands are treated as micro-shearing of rank-one laminates. It is

Strain-dependent localization, microscopic deformations, and macroscopic normal tensions in model polymer networks [PDF]
, 2004 We use molecular dynamics simulations to investigate the microscopic and macroscopic response of model polymer networks to uniaxial elongations. By studying networks with strands lengths ranging from $N_s=20$ to 200 we cover the full crossover from cross-

Strain Localisation and Fracture of Nuclear Reactor Core Materials
Journal of Nuclear Engineering, 2023 The production of prismatic dislocation loops in nuclear reactor core materials results in hardening because the loops impede dislocation motion. Yielding often occurs by a localised clearing of the loops through interactions with gliding dislocations ...

Volumetric and Shear Strain Localization in Mt. Etna Basalt
Geophysical Research Letters, 2019 To examine the impact of preexisting weaknesses on fracture coalescence during volcanic edifice deformation, we triaxially compressed Mount Etna basalt while acquiring in situ dynamic X‐ray microtomograms and calculated the internal strain tensor fields ...
