Three-Dimensional Geostatistical Analysis of Rock Fracture Roughness and Its Degradation with Shearing
Three-dimensional surface geometry of rock discontinuities and its evolution with shearing are of great importance in understanding the deformability and hydro-mechanical behavior of rock masses. In the present research, surfaces of three natural rock fractures were digitized and studied before and after the direct shear test. The variography analysis of the surfaces indicated a strong non-line...
متن کاملFriction and roughness of a melting rock surface
S U M M A R Y Under extreme conditions like those encountered during earthquake slip, frictional melt is likely to occur. It has been observed on ancient faults that the melt is mostly extruded toward local extensional jogs or lateral tension cracks. In the case of laboratory experiments with a rotary shear apparatus, melt is extruded from the sample borders. When this happens, a thin and irreg...
متن کاملEffect of surface roughness on steel-steel dry friction coefficient
The influence of surface roughness magnitude and direction on dry static friction coefficient between two similar steel samples has been studied through an experiment. A testing apparatus has been designed and fabricated to measure the friction coefficient for a few forms of surface asperity. According to the results of the experiments, dry friction coefficient is affected by both magnitude and...
متن کاملTHE EFFECT OF OPACIFIERS ON SURFACE ROUGHNESS OFCERAMIC GLAZES
Surface smoothness of ceramic glazes is always an important characteristic of ceramic glazes as a point of surface engineering studies. Surface roughness affects chemical resistivity, glossiness and stainabiliy of glazes. In fact, less surface roughness improves cleanability of the surface by the least usage amount of detergents. In this investigation, surface topography of two common opaque gl...
متن کاملA comparetive study of the effects of home and office bleaching on enamel surface roughness
Introduction: Increase in enamel surface roughness after bleaching is one of its major side effects. The purpose of this study is to compare changes in enamel surface roughness following bleaching with home versus office bleaching agents. Materials and Methods: In this experimental study, forty human sound premolar teeth were divided into 4 groups, randomly. Ten teeth were bleached using hydrog...
