group_materi_elasti_camclay_poisson index $\nu $

Elastic data $\nu $ for the modified CamClay model. This option is alternative to the group_materi_elasti_camclay_g option (so, only one of both can be defined). With this option the poisson ratio $\nu $ is assumed constant, and is used as follows:

G = \frac{3}{2} K ( 1 - 2 \nu ) / ( 1 + \nu )

The index specifies the element_group, see element_group.
