COMPRESSION AND EXTENSION OF K SUB O NORMALLY CONSOLIDATED KAOLIN CLAY. DISCUSSION
This is a discussion of a paper of the above title by J.H. Atkinson, D. Richardson, and P.J. Robinson published in Volume 113, No. 12 (December 1987) of this journal. The discussers note that the use of triaxial extension (TE) test data to deduce the state boundary surface and, subsequently, the yield surface of clays may be misleading, and a better approach would be to obtain the form of the yield locus first, using experimental data, and then to deduce the state boundary surface from the yield locus. This requires experimental data from more than only triaxial shear tests. The discussers believe that the initial part of the stress path in TE is elastic and therefore the TE test data cannot be used to deduce the state boundry surface of clays in general. Furthermore, the existing data suggest that the critical state lines in TE and TC are asymmetrical about the p' axis. These comments are followed by a closure by the author, J.H. Atkninson.
