We evaluate the parameters that control the thickness of ductile shear zones that are generated by viscous heating. We employ two-dimensional thermomechanical numerical models to simulate shear zone development under compression. Results show that the shear zone thickness is essentially independent on the numerical resolution and the initial size of a weak inclusion that triggers shear localiza...

Compressive and extensive horsetails are common structures on the lateral termination of brittle strike-slip faults, which forms within the shallow continental crust. Here we report another possibility, the lateral termination of a brittle strike-slip fault in a formation-parallel low-temperature ductile shear zone within sulphatic, gypsum-dominated evaporites. In the Southern Alps, over a dist...

the khushab anticline is located in the zagros fold-thrust belt in the lurestan. this anticline is affected by the balarud fault zone, which is a part of mountain front fault between the lurestan and dezful embayment zones. based on the measurement of the elements of fold style, this anticline is analyzed. according to these measurements, this anticline is a noncylindrical, asymmetrical and dis...

F-actin microfilament reorganization in response to alterations in shear stress has not been experimentally tested in vivo. In the current study, we analyzed changes in F-actin distribution in endothelial cells around the site of a coarctation performed in the midabdominal aorta of rabbits. The coarctation caused a 60% decrease in luminal diameter and produced three distinct zones: 1) a high sh...

Flow recirculation zones and shear rate are associated with distinct pathogenic biological pathways relevant to thrombosis and atherogenesis. The interaction between stenosis severity and lesion eccentricity in determining the length of flow recirculation zones and peak shear rate in human coronary arteries in vivo is unclear. Computational fluid dynamic simulations were performed under resting...

Investigating the behavior of the box-shaped column panel zone has been one of the major concerns of scientists in the field.  In the American Institute of Steel Construction the shear capacity of I-shaped cross- sections with low column thickness is calculated. This paper determines the shear capacity of panel zone in steel columns with box-shaped cross-sections by using artificial neural netw...

The reported study examines the dynamics of entrainment and its effects on the evolution of the dry atmospheric convective boundary layer (CBL) when wind shear is present. The sheared CBL can be studied by means of direct measurements in the atmosphere, laboratory studies, and numerical techniques. The advantages and disadvantages of each technique are discussed in the present paper, which also...
