... vibration applied, torsional or flexural, shear and compression wave velocities are secured. By varying the amplitude of vibrations applied, various strain levels can be introduced and corresponding resonant frequencies and wave velocities can be calculated. The resonant column experiments were performed...

... that comparison of strains may be a better approach as the deformations are easily measurable. Critical strain is defined as that strain level beyond which the squeezing problems will be likely to occur. It is shown that the critical strain depends on properties of rock material, configuration of joints...
