Mechanical Behavior of Rock-Like Specimens .

The mechanical behavior of rock mass is strongly influenced by internal joints. To investigate the effect of hidden joints on the strength and deformation behavior of rock mass, a series of triaxial compression tests was carried out using specimens made from rock-like material. In the experiments, a self-designed pouring apparatus was used to prepare specimens with hidden smooth joints at a ...

Modeling and numerical analysis of granite rock .

Abstract: The effect of ISO 834 fire on the mechanical properties of granite rock specimen submitted to uniaxial loading is numerically investigated. Based on Newton's second law, the rate-equation model of granite rock specimen under mechanical load and fire is established. The effect of heat treatment on the mechanical performance of granite is analyzed at the center and the ends of specimen.

rock specimen under mechanical load and fire is established. The effect of heat treatment on the me-chanical performance of granite is analyzed at the center and the ends of specimen. At the free end of granite rock specimen, it is shown that from 20 Cto500C, the internal stress and internal strain are weak; whereas above 500 C, they start to increase rapidly, announcing the imminent collapse ...

Notch (engineering) - Wikipedia

In mechanical engineering and materials science, a notch refers to a deliberately introduced v-shaped, u-shaped or circular defect in a planar material. In structural components, a notch causes a stress concentration which can result in the initiation and growth of fatigue cracks. Notches are used in materials characterization to determine fracture mechanics related properties such as fracture ...

Triaxial shear test - Wikipedia

A triaxial shear test is a common method to measure the mechanical properties of many deformable solids, especially soil (e.g., sand, clay) and rock, and other granular materials or powders.There are several variations on the test. In a triaxial shear test, stress is applied to a sample of the material being tested in a way which results in stresses along one axis being different from the ...
