Local strain measurements during electromigration

AIP Conference Proceedings, 1999
This paper reviews the measurements of local strain distribution in individual 10 μm-wide 200 μm-long passivated Al conductor lines using white-beam x-ray microdiffraction. Local strain changes were examined in real-time when the Al lines were subjected to temperature changes as well as to electrical current stressing.

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 ...

Strain localization in multipotential elastoplasticity

International Journal for Numerical Methods in Engineering, 1992
AbstractConditions of strain localization in multipotential elastoplasticity are studied in this paper for a strain discontinuity mode. The formulation is specialized to the case of a general anisotropic Mohr‐Coulomb model, where plastic shear deformations are envisaged as the contribution of microstrains in several planes.

Strain localization under dynamic loading

Technical Physics, 2013
A spallation model of strain localization is suggested according to which localization bands under pulsed loading result from unloading wave interference such that negative stresses in the extension zone are lower than the ultimate strength of the material.

Local Strain Energy Density Concept

2013
The local strain energy density (SED) approach is elaborated for strength assessments in respect of brittle fracture and high-cycle fatigue. Pointed and rounded (blunt) V-notches subjected to tensile loading (mode 1) are primarily considered, occasionally extended to multiaxial conditions (mode 3, mixed mode 1 and 2).

Objective modeling of strain localization

Revue Française de Génie Civil, 2002
ABSTRACT This paper provides an elementary introduction into modeling of localized inelastic processes such as cracking or formation of shear bands. The basic concepts are explained using a simple one-dimensional example. It is shown that a stress-strain law with softening used in a standard continuum description leads to physically meaningless results

On brittle-ductile strain localization

2020
<p>The classification of the strain localization modes is attempted around brittle-ductile transition. The stresses are high. The are a number of suspects: earthquake-like thermal runaway (Braeck et al. 2009), stable sliding as shear heating zones oriented 45 degrees to the principal stresses (Kiss et al.

Strain Localization in Granular Materials

1998
Contemporary localization theory [99] is a natural extension of Mohr’s [50] original strength theory published in the year 1900 in a milestone paper with the title, “Welche Umstande bedingen die Elastizitatsgrenze and den Bruch eines Materials?”. Mohr’s question cannot be answered without resorting to experiments carefully and systematically run ...
