Mathematics and Mechanics of Solids, 2010
Based on previous work of the first author, the local sufficient condition of uniqueness of the solution of the incremental boundary-value problem in generalized elastoplasticity which excludes the possibility of bifurcation state is compared with the local necessary condition for the localization of plastic deformations as a Rice—Rudnicki ...

Local Strain Measurement within Tendon
Strain, 2004Abstract: Tendon is a dense connective tissue, responsible for transmitting the forces generated by muscles to the skeleton. It is composed of a hierarchical arrangement of crimped collagen fibres, interspersed with proteoglycan matrix and cells, known as tenocytes.

Plastic strain localization in Bouligand structures
Journal of the Mechanical Behavior of Biomedical MaterialsThe Bouligand structure represents helicoidal stacking of aligned fibers; such a structure is widely observed in biological composites. Despite the progress in characterization of toughening caused by Bouligand arrangement of fibers, the inelastic deformation mechanisms of this structure remain elusive.

Strain localization in amorphous metals
Acta Metallurgica, 1982Abstract Inhomogeneous flow in metallic glasses is studied in this paper within the context of continuum mechanics. Motivated by similar work for elastic-plastic solids, the possibility of strain localization into a shear band is investigated for a metallic glass which is modelled as a nonlinear viscoelastic solid.

Local strain distribution analysis in strained SiGe spintronics devices
Extended Abstracts of the 2023 International Conference on Solid State Devices and Materials, 2023Abstract This paper reports nanobeam X-ray diffraction (nanoXRD) measurement results for strained SiGe spintronics devices grown by MBE. A quantitative nanoXRD analysis verifies that in-plane strain is properly exerted on the SiGe spin channel layer in the device showing enhanced spin diffusion length, whereas overall strain relaxation ...

Strain localization and porphyroclast rotation
Geology, 2011It has been debated for decades whether rigid inclusions, such as porphyroclasts and porphyroblasts, do or do not rotate in a softer matrix during deformation. Experiments and numerical simulations with viscous matrix rheologies show ongoing rotation of circular inclusions, whereas using Mohr-Coulomb plasticity results in nonrotation. Because the rocks

Heat conduction effects on strain localization in plane‐strain tension
International Journal for Numerical Methods in Engineering, 1995AbstractThe deformation behaviour of a rectangular block under tension is investigated for a rate‐ and temperature‐dependent solid using the finite element method. Isotropic behaviour is assumed and the effect of deformation‐induced heat generation is studied in conjunction with heat conduction. Localization into diffuse necking is examined by applying

Adiabatic Deformation and Strain Localization
1981The strain localization phenomenon of “adiabatic shear” is generally attributed to a plastic instability arising from a thermal softening effect during adiabatic or near-adiabatic plastic deformation. High strain-rate adiabatic torsion tests indicate that the effective shear stress-strain \((\bar \tau - \bar \gamma ) \) relations for high-strength ...
