An accurate determination of Hoek–Brown constant mi is of great significance in the
estimation of the failure criteria of brittle rock materials. So far, different approaches such as …

Rock formations experience strength and stiffness degradation or enhancement, which is
often reflected by an increase or decrease in the elastic constant. Such elastic constant …

Under conditions of low or medium stress, rocks that are in the compression state exhibit
perceivable nonlinear elastic characteristics. After a comprehensive review of the existing …

Determining linear elastic stiffness parameters is a crucial aspect of ground characterization
that enables subsequent numerical analyses using finite element, discrete element, and …

The most common classification method of drill cores is the Rock Quality Designation (RQD)
value, which indicates the percentage of rock cores longer than 10 cm in a given core …

Any rock mechanics' design inherently involves determining the deformation characteristics
of the rock material. The purpose of this study is to offer equations for calculating the values …

The freezing technique has been employed for a long time to strengthen the mechanical
properties of intact rock and rock mass; however, it has not received as much attention as it …

Geomechanical properties such as uniaxial compressive strength (UCS) and modulus of
elasticity (E) are essential for evaluating the mechanical behavior of rocks and crucial for …

Heat-induced physical changes of rocks, as would happen in fire accidents, have crucial
importance in the long-term stability of underground openings such as tunnels or radioactive …

The size effect on the bulk modulus of rocks has been reported by previous studies. The
accuracy in selecting the parameter for the rock mechanics analysis determines further …
