A K0 consolidated-undrained triaxial compression (σcell = constant) test was conducted on an undisturbed specimen of sensitive Swedish clay. The initial conditions were as shown in Fig. The stress-strain and pore pressure responses of the specimen are shown in Fig.

(a) Find the stress conditions at failure and symbolically show the total, neutral, and effective stresses (like the “initial conditions” shown above).

---

(b) Sketch the total and effective stress paths.

(c) Plot A versus ɛ. What is Af? What are ϕ′ and ϕT
