The authors attempt to revive the isotache concept using the C a /C c law of compressibility. However, a fundamental limitation of the authors' approach leads them to reach incorrect and misleading conclusions about the magnitude and behavior of C a /C c . The objective of this discussion is to clarify that the authors' parameter D log p c /D log _ e vp is not necessarily equal to C a /C c (where C a ¼ De/D log t, C c ¼ De/D log s 0 v in recompression and compression range, e ¼ void ratio, t¼
