Notes: Consolidation stress = difference between confining and internal pore pressure prior to shear. "A" coefficient at failure = change in pore pressure/change in deviator stress, q = shear stress acting on a plane inclined 45° from the horizontal, (1 – 3)/2, p´ = normal effective stress acting on a plane inclined 45° from the horizontal, (´1 + ´3)/2, ´max = maximum friction angle in terms of effective stresses, passes through the origin.
