Numerical determination of scale effect and anisotropy of strength and deformability in jointed rock masses

Rock masses are inherently discontinuous and anisotropic due to the presence of joints, and their equivalent mechanical behaviour exhibits strong scale dependence. A key challenge is to determine the representative elementary volume (REV) at which mechanical properties stabilise....

Systematic numerical evaluation of the influence joint geometrical and mechanical parameters on the REV of rock masses

Abstract The Representative Elementary Volume (REV) is a key concept in the analysis and simulation of jointed rock masses, playing a crucial role in selecting the dimensions of laboratory samples and the domain size of numerical models. However, a precise understanding of the in...
