A constitutive model for jointed rock masses

A constitutive model for the deformation of a rock mass containing sets of ubiquitous joints

“…(7) governs the deformation induced by joints [15,16,18,21,28]. The four terms, D st , D ts , D sn , and D tn , represent the deformation at one direction induced by the stress acting at another direction and are expected to be negligible since the intact rock is rather rigid, instead of jelly-like material.…”

“…Computational approaches based on continuum mechanics, in which the influence of joints is considered through the concept of the so-called representative volume elements, have been proposed [14][15][16][17][18][19][20][21]. These models can further estimate the anisotropic strength and deformation of rock masses until the load reaches the peak strength.…”
