<p>Rheological models of Earth&#8217;s granitoid mid- to upper crust are commonly based on the physico-chemical properties of the most abundant rock forming minerals quartz and feldspar. However, there is increasing field evidence that deformation in these rocks localizes in ultrafine-grained polymineralic shear zones, which are ...

Strain localization in geomaterials
Geological Society, London, Special Publications, 2007Abstract The main purpose of this paper is a broad review of developments in observation and interpretation of localization in geomaterials in the laboratory, with an emphasis on low mean stress situations. Laboratory investigation of strain localization in granular soils and rocks has been pursued extensively and very accurate strain field ...

Local Plastic Strain Measurement by EBSD
Applied Mechanics and Materials, 2007Work has been carried out recently, which demonstrates misorientation measurements recorded by using electron backscatter diffraction (EBSD) enables one to undertake local post mortem plastic strain quantification once the degree of misorientation is calibrated against plastic strain.

Strain localization phenomena such as necking and shear banding very often occur prior to final failure. They can be predicted by a bifurcation analysis of the system of constitutive and equilibrium equations. Notions like stability, acceleration waves and loss of ellipticity are defined. Finite element simulations can be performed to predict the onset

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 ...
