Unformatted text preview: lnp', v = constant (because it is an undrained test) and the critical state is reached at the same value of p' as sample A. On the graph of q against p', p' = constant (= 140 kPa) until the undrained state boundary is reached. The effective stress path then follows the undrained state boundary to failure at the same point as sample A. This is shown in Figure Q5.7c (note: ln 140 = 4.94; ln200 = 5.30)....
