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 ...

Deformation within a steady-state compressional orogen, i.e., where tectonic accretion is, on geological time scales, balanced by surface erosion, can best be described by a stationary velocity field. Instantaneous deformation results from spatial gradients in the velocity field, whereas total accumulated strain results from the integration of this ...

Modelling of strain localization in a large strain context
Structural Engineering and Mechanics, 1996In order to avoid pathological mesh dependency in finite element modelling of strain localization, an isotropic elasto-plastic model with a yield function depending on the Laplacian of the equivalent plastic strain is implemented in a 4-node quadrilateral finite element with one integration point based on a mixed formulation derived from Hu-Washizu ...

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 localization

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.

Residual strain and local strain distributions in the rabbit atherosclerotic aorta
Journal of Biomechanics, 1995Effect of atherosclerosis on the residual strain in the arterial wall was studied in the rabbit thoracic aorta. Atherosclerosis was induced by feeding a cholesterol diet or by combining denudation of aortic endothelial cells with the diet feeding. Diameter of each aorta in the physiological state was determined from a static pressure-diameter test.

<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 ...
