... ABSTRACT: The evolution of physical and mechanical properties of four sets of different marble rocks after different thermal treatments was investigated. Marble rocks are indeed natural stones extensively used during ancient times in many archaeological sites, cultural heritage artefacts...

... the linearized, quasi-static Navier-Stokes equations describing laminar flow of a compressible viscous fluid inside the cracks and pores coupled with the quasistatic Lamé-Navier equations for the solid phase. A thermally treated (thus cracked) Carrara marble sample was employed, and we consider it fully...

... stress and its orientation is also an important aspect to consider since it allows a correct and realistic calibration of the numerical model. In the Carrara basin, located in the Apuan Alps (Central Italy), there are many large underground marble quarries that have been monitored in the last years...

...Abstract Abstract This work aims to reveal the physical process and nonlinear mechanical behaviors of marble under the fatigue cyclic and triaxial confining pressure unloading conditions. The GCTS RTR 2000 rock mechanics testing machine was first used to perform the triaxial confining pressure...

... Abstract The study of failure mechanisms of excavation damage zone plays a key role in the stability analysis of surrounding rocks. Typical true triaxial compression tests are carried out on marble taken from the China Jinping Underground Laboratory phase II under different σ 2 and very low σ...

... Abstract The bowing in marble is a well-known phenomenon and it has been studied along the last decades; however, the key mechanisms responsible to cause this pathology are not well agreed between the experts. Some approaches to model this phenomenon were done by different authors considering...

... is granite which is an igneous rock that is polymineralic, the other is marble which is monomineralic and relatively homogeneous. The mineral content and grain structure of two rock types are identified using petrographic thin sections. The strain rate effect of rock shear strength under triaxial confining...

... ABSTRACT: The mechanical behavior of Zhenping marble is studied using the lattice-spring-based synthetic rock mass (LS-SRM) modeling approach. Mechanical response of the rock is assessed using stress–strain relations under unconfined and confined compressions. ITASCA's SRMTools is used...

... Abstract Information of subcritical crack growth in rock is essential to ensure the long-term integrity of a rock mass surrounding various structures and various architectures made of rock materials. In this study, using Carrara marble as a rock sample, subcritical crack growth...

... Abstract Marble quarries, are located at 3 km southeast of the city of Afyon İscehisar. The marble bed is lens shaped has a thickness of 300 meters. İscehisar is on south of the city center and marble bed extends through NW-SE direction for 6 km long and 1.5 km wide. Present base elevation...

... Abstract: In this study three series of indirect tensile tests, the Brazilian test, the flattened Brazilian (FB) test and the ring test, were performed in order to determine the indirect maximum tensile stress of Dionysos marble. A number of circular disc specimens ( D = 54 mm) was prepared...

... Abstract The Marble Falls play in North Texas is a highly economic liquids-rich play that unconventional technology has resurrected from an old lackluster trend. Historically, >2,500 wells have produced from conventional traps in the MBLF. They traditionally employed simple perf-and-acid...

... Abstract A serials of loading-unloading experiments of marble in Jinping II hydropower station, China, are carried out to investigate its failure mechanism under complex stress condition. It is found that, the marble failure process is divided into five stages, including initial crack closure...

... Abstract In this paper, a number of experimental tests are carried out to study the strength difference on rectangular prismatic marble specimens with different height-to-width ( H/W ) rations. The specimens have a nominal size of 45 × 15 mm in the compressive cross-section ( W × T...

... ABSTRACT: A general framework for probabilistic damage in rock using maximum entropy theory is proposed to describe the failure process of marble from hydropower station at Jinping II, China. In this paper, the failure process of marble is divided into three stages. In the first stage...
