..., Newland & Allely 1957). The shear strength models have taken into account joint surface roughness, an angle of asperities, an effect of normal stress acting on a joint on dilatancy, and infill materials, resulting in a large difference from the peak shear strength derived from Mohr-Coulomb criterion...
