Plastic strain localization in Bouligand structures

Journal of the Mechanical Behavior of Biomedical Materials
The 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.

Heat conduction effects on strain localization in plane‐strain tension

International Journal for Numerical Methods in Engineering, 1995
AbstractThe 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

Strain Localization in the Dent of a Linepipe

Volume 2: Pipeline Integrity Management, 2014
Steel pipelines used for transporting oil and gas can develop various damages such as mechanical damages, corrosion, wrinkle, and crack. One of the mechanical damages is a dent with or without other defects such as corrosion, gouge, and crack. The dent without other defect is often referred to as plain dent.

Strain localization and porphyroclast rotation

Geology, 2011
It 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

Strain localization in amorphous metals

Acta Metallurgica, 1982
Abstract 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.

Plastic Deformation and Strain Localizations

2020
This chapter gives an overview of basic knowledge on plastic deformation and strain localizations. The chapter starts with general remarks on plastic deformation continuing with details on deformation mechanisms such as dislocation glide and twinning were shortly summarized focusing for most common crystal lattices in metallic materials: (i) face ...

Local Phonons in Strained Superlattices

1993
Calculations based on a planar force-constant model for strained-layer superlattices (SLSs) are presented. The calculations are compared with the experimental results of Raman scattering by optical phonons in GaP/InP and AlAs/InAs SLSs. The local character of some of the optical phonons of these superlattices has been used to study the electronic ...
