The normalised shear modulus and material damping ratio curves for various joint spacings and confining pressures have been produced. The modified hyperbolic and Ramberg-Osgood models were used to fit curves based on experimental data...

When the value of this parameter is equal to one, the critical fraction of rotating blocks causing the loss of stability is zero...

The approach to uniaxial strain with decreasing aspect ratio is slower if the shear modulus of the inhomogeneity exceeds that of the surrounding material. Depletion or withdrawal...
