THE ANALYSIS OF THE STRAIN STATE OF SHEAR ZONES IN TERMS OF  TYPES OF SECONDARY FRACTURES: STATEMENT OF PROBLEM

open access: yesГеодинамика и тектонофизика, 2015
Introduction. In this publication, shear zones, being traditional objects of tectonophysical studies, are considered in terms of their strain states. This approach differs from a commonly applied one when shear zones are studied with consideration of ...

Shear banding in metallic glasses described by alignments of Eshelby quadrupoles [PDF]

open access: yes, 2017
Plastic deformation of metallic glasses performed well below the glass transition temperature leads to the formation of shear bands as a result of shear localization.

Spatial variation characteristics of shear wave velocity structure and its application to quaternary deep sediment layers in Suzhou region

open access: yesYantu gongcheng xuebao, 2018
The shear wave velocity of soils is one of the most important parameters to evaluate the seismic effects of engineering sites. Based on large numbers of borehole shear wave velocity measurements and the engineering geological characteristics in Suzhou ...

Structural features and emplacement of the late Svecofennian Perniö granite sheet in southern Finland [PDF]

open access: yesBulletin of the Geological Society of Finland, 1996
The 1840-1830 Ma old Perniö granite occupies the southern margin of the Sauvo-Perniö granite area located in the western part of the late Svecofennian granite-migmatite zone in southern Finland.

Scale-dependent influence of pre-existing basement shear zones on rift faulting : a case study from NE Brazil [PDF]

open access: yes, 2013
Rifting of continental crust initiates faults that are commonly influenced by pre-existing structures. We document newly identified faults cutting Precambrian units in the interior of the NE Brazilian margin to assess the effects of structural ...

Microstructure of shear zones in Fontainebleau sandstone [PDF]

open access: yesInternational Journal of Rock Mechanics and Mining Sciences, 2002
On the basis of image analysis, porosity and grain-size changes have been studied inside the shear bands formed in triaxial testing on a Fontainebleau sandstone. For this rock the shear band is characterized by a white coloration visible to the naked eye.

Distribution, characteristics, ages, and tectonic environments of ductile shear zones in the Beishan orogenic belt

open access: yesDizhi lixue xuebao
Objective  The Beishan occupies a pivotal position between the eastern and western segments of the Central Asian Orogenic Belt (CAOB). Although numerous ductile shear zones have been identified in this area, they have received limited attention, leading ...

Structural and hydrogeological features of Pleistocene shear zones in the area of Rome (Central Italy)

open access: yesAnnals of Geophysics, 1994
The last tectonic episode observed in the Latium Tyrrhenian margin (Central Italy), few km cast of Rome, is represented by a set of middIe-upper Pleistocene N-S shear zones, characterised by complex geometric and kinematic setting.

Strain localization in a shear transformation zone model for amorphous solids

open access: yes, 2007
We model a sheared disordered solid using the theory of Shear Transformation Zones (STZs). In this mean-field continuum model the density of zones is governed by an effective temperature that approaches a steady state value as energy is dissipated.
