Nonlinear shear behavior of rock joints using a linearized implementation of the Barton–Bandis model
Journal of Rock Mechanics and Geotechnical Engineering, 2017 Experiments on rock joint behaviors have shown that joint surface roughness is mobilized under shearing, inducing dilation and resulting in nonlinear joint shear strength and shear stress vs. shear displacement behaviors.
