A fixed-free rod is heated uniformly by an amount of ΔT. The rod experiences axial and transverse strains due to temperature increase; however, no stress is developed since the right end of the rod is ...

To study the influence of control mode and loading rate on mechanical property of rock, uniaxial compression tests of four types of rocks (gray sandstone, red sandstone, mudstone and granite) are ...

With the continuous advance of coal mining, the normal stress in front of coal seams will continue to increase, resulting in changes of internal structure and permeability of coal seams. During the ...
