Figure 9. Original Cam Clay in one picture. The left hand plot shows the yield surface (blue) with plastic strain increment vectors (pink) normal to the yield surface. The right hand plot shows e-log(p) with CSL in green. The points linked in red are common to both plots – as void ratio changes, so does the size of the yield.
