Fluids are pervasive in the Earth’s crust and saturate fractures faults. The combination of fluids gouge layers developing along faults can generate different viscosities. Such viscous were found to influence reactivation, frictional stability faults, eventually dynamics propagating earthquake ruptures. We reproduced laboratory earthquakes on analog material (PMMA) study lubricant fault stabili...

Understanding the folding style of a fold-thrust belt is crucial to understand the nature and structural history of structures that may trap natural resources within the belt. In this research, the geometry and mechanism of a number of fault-related folds has been investigated based on field data and satellite image interpretations. The main study areas are: the Sohrevard and Ushtaniyan anticli...

Finite strain and vorticity analyses were carried out in the deformed conglomerate and micro-conglomerate of Goushti shear zone in the Sanandaj-Sirjan metamorphic belt (Zagros Mountains Iran). These deformed rocks are bounded between two NE and SW major thrust faults. Finite strain measurements on three principal planes of strain ellipsoid show the higher amounts of strain ratios near the major...

this study was conducted in order to evaluate the effects of long term ageing on toughness andresilient modulus of asphalt concrete mixtures containing electric arc and basic oxygen furnacesteel slags. after initial evaluation of the properties of steel slags using x-ray diffraction andscanning electric microscope, eleven sets of laboratory mixtures were prepared. each set wastreated replacing ...

abstract background: distal radial fracture is one of the most common fractures of the skeletal system. although it has been believed to be a simple fracture with excellent outcomes, practical operations’ results have always been undesirable and even poor. the goal of this study was to compare two methods of treatment “pin and plaster and precautious pin fixation in patients with unstable extra...

This paper addresses the design of an observer-based fault diagnosis scheme, which is applied to some of the sensors and actuators of a wind turbine benchmark model. The methodology is based on a modified sliding mode observer (SMO) that allows accurate reconstruction of multiple sensor or actuator faults occurring simultaneously. The faults are reconstructed using the equivalent output err...

Introduction: Among the classic field-and laboratory studies of crater structure, a handful have mentioned the influence of fracture networks upon crater shapes [1,2,3] and few later investigations have addressed the problem directly (see [4] for a recent study and thorough review). A polygonal simple crater is thought to result when the excavation flow exploits planes-of-weakness in the target...

In this study, we analyze the fault and fracture network of Middle Triassic carbonate platform Lastoni di Formin (Italian Dolomites, Italy). The reconstruction deformation history is primary importance for a full comprehension present structural setting platform. huge dimensions body superb exposure its vertical cliffs gently dipping top plateau make an ideal outcrop to integrate traditional fi...
