Investigating the Macro-Micromechanical Properties and ...

When the stress increases to about 100 MPa (i.e., 78% of the peak strength), there is a rapid microcrack growth in the specimen, and the strength corresponds to the crack damage strength σ cd. When it comes to reach the peak strength, the number of cracks begins to increase significantly, and the macrofailure surface is gradually formed.

Granite - Wikipedia

Granite (/ ˈ ɡ r æ n. ɪ t /) is a coarse-grained igneous rock composed mostly of quartz, alkali feldspar, and plagioclase.It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground.It is common in the Earth's continental crust, where it is found in various kinds of igneous intrusions.These range in size from dikes only a few ...

1. Introduction

During the hot dry rock mining, because surrounding rocks are mainly composed of granite, the main construction method is hydraulic fracturing; the hydraulic pressure strength and the shape of water fracture are the most important aspects to be focused [1 – 3].For multicomponent crystalline rocks such as granite, the strength characteristic and fracture distribution are related to the ...

Dec 01, 1985  The 9 groups, containing the remaining 126 specimens, were subjected to long- term loading at constant load, ranging from 155 to 215 MPa. This corresponds to loading between 69 and 95% of the mean dry compressive strength. The desired outcome of each test was the "time to failure" or "failure time" (TTF), and these are listed in Table 1.
