Models by Jean Biarez for the Behavior of Clean Sands and Remolded Clays at Large Strains - Multiscale Geomechanics: From Soil to Engineering Projects - page 128

Let us note that only the remolded clay-sand mixtures with w L < 24 can be found
in this category.

5.6.2. Modeling of the maxima under the right M on the plan q - p'

Lee and Seed [LEE 67] presented four outstanding tests (see Figure 5.13) on
Sacramento sand, three with a peak in the (q - ε 1 ) plane for high stresses and
maxima under the M line.
