Shear localization has been observed in liquid lubricants flowing at high pressure. Two kinds have been identified: for stresscontrolled plane Couette shear at high values of Nahme No., thermal runaway can result in the appearance of a band at midplane where the temperature and shear rate become localized. Alternatively, at high pressure and high shear stress, intermittent slip can be visualize...

Abstract There are still two deficiencies in the study of crack propagation plane steel. One is that there few studies on theory cracking and criterion from strain field at tip; other using block discrete element method to explore propagation. In view above points, this paper proposes a strength explain extension tensile cracks shear This assumes: (1) Tensile grow along direction maximum princi...

Landslide stability analysis is the basement of landslide research. To study influence water on reservoir stability, taking a for example in hydroelectric power station based detailed field investigation and operation data, geological conditions, rainfall were considered, slope failure pattern under natural state rain simulated with Mohr-Coulomb criterion after an numerical three-dimensional mo...

We investigate the infrared limit of the quantum equation of motion of the gauge boson propagator in various gauges and models with a BRST symmetry. We find that the saturation of this equation at low momenta distinguishes between the Coulomb, Higgs and confining phase of the gauge theory. The Coulomb phase is characterized by a massless gauge boson. Physical states contribute to the saturation...

background : gastric cancer is the one of the most prevalent reason of cancer-related death in the world. survival of patients after surgery involves identifying risk factors. there are various models to detect the effect of risk factors on patients’ survival. the present study aims at evaluating these models. methods : data from 330 gastric cancer patients diagnosed at the iran cancer institut...

In order to research the displacement characteristics and stability of a soil slope reinforced with carbon-fiber-reinforced plastic (CFRP) anti-slide piles, composition, aging deformation failure mode mass were analyzed. According Mohr–Coulomb strength criterion, new nonlinear, accelerated creep model was founded addition self-building M-C element. Furthermore, viscoplastic strain analytical fo...

In this research work, a 3D numerical modeling technique is proposed based on the 3D particle flow code in order to investigate the failure mechanism of rock foundations. Two series of footings with different geometries and areas are considered in this work. The failure mechanism obtained is similar to that of the Terzaghi’s but there is a negligible difference in between. Lastly, one equation ...
