... Abstract Mechanical characteristics and energy properties of granite under uniaxial compression after high temperature have been researched. The results show that energy conversion during rock deformation and failure is a dynamic process, and it can be mainly divided into four subprocesses...

... obtained, and the efficiency can get much higher. Finally, numerical results are given to illustrate the efficiency of the present method. Instruction Natural rocks in the engineering are often under the compression states, with the defects and nonuniformity, they are often rich in joints and cracks...

... failure plane is formed. In order to study the strength properties of such microfissure rocks, and provide basic data for investigating the water inflow and mud burst mechanism of tunnel excavated in microfissure-well-developed rocks, a series of triaxial compression tests under different loading path...

... Abstract In order to study the time-dependent deformation behavior of bedding anisotropy greenschist of Jin-ping II Hydropower Station, uniaxial and biaxial compression creep experiments were carried out. Vertical loadings were perpendicular or parallel to bedding planes, which were graded 4...

... Abstract This paper presents a pilot numerical study into the rolling compression induced disintegration modes of a coal prism within a mill of vertical roller type. To simulate the breakage process characterized by large deformation and the transition from continuum to discontinuum, the coal...

... ABSTRACT Perhaps the most important mechanical property of rock is its compressive strength. Strength criteria such as the Coulomb, Mohr, or Hoek-Brown, are strictly correct only when the intermediate and least principal stresses are equal (σ 2 = σ 3 ). At the University of Wisconsin we...
