Zhao et al. 2019 observed that the peak shear strength of granite fractures decreased with the increase in treatment temperature from 20 to 400 c. khamrat et al. 2018 found that, even for the same rock tak granite, the shear strengths of rough and smooth fractures exhibited different evolution trends with the increase in temperature ...
1the peak shear strength of granitic test specimens was between 0.8 and 4.1 mpa, depending on the surface and joint fill. key words direct shear strength, granite, radioactive waste disposal, joint, angle of friction introduction shear strength tests play an important role in assessing the behavior of rock masses.
9note that in general, the tensile strength measured using the indirect methods is less than that measured used a direct tension apparatus. 2.5 shear tests direct simple, double or punch shear tests can be conducted on rock. the tests allow a direct measurement of the intact rock shear strength. however, they are difficult to perform.

The three-dimensional morphology3d of a rock joint has a great impact on its shear behavior. in order to study the relationship between the characteristics of three-dimensional morphology and the peak shear strength of rock joints,the rock samples with fresh ...
Strength is considered in terms of compressive strength, tensile strength, and shear strength, namely the limit states of compressive stress, tensile stress and shear stress, respectively2. according to reference 3, the effect of dynamic loading is probably the most important practical part of the strength of materials, especially the problem of fatigue.
3shear stress is the shear strength of the soil for the particular value of the normal force n or normal stress na applied to the soil, where a is the cross sectional area of the soil sample. fig. 8.8 shows that a dense sand has a greater shear strength than a loose sand and this strength is reached at a smaller value of the displacement.
Shear strength and permeability of granite residual soil contaminated with urban solid waste leachate ... the results showed that the shear strength is similar to that of clean soil and the permeability slightly decreases, which might occur due to the clogging of preferential paths by the fines or because of differential consolidation effects. ...
The strain rate effect of rock shear strength under triaxial confining conditions has been studied by controlling the impact velocity of the striker. both rock types exhibit strain rate effect with increasing shear strength granite has higher shear strength and failure strain, while marble has lower shear streng.
In term of shear strength, there are three shear strength parameters that are required to define a failure envelope of an unsaturated soil, which is an extended form of the mohr-coulomb equation fredlund et aly 1978. they are cy apparent cohesion, py effective angle of friction, and 0 shear strength change with change in matric suction.

Peak shear stiffness and displacement the shear displacement peak required to reach peak shear strength determines the stiffness of joints in shear. this is extremely important input data in finite element analyses of jointed rock, since joints are very deformable in shear compared to the normal direction and compared to the intact rock b a r t o n , 1972.
