Good one.. thanks.

@plaxistutorial Suggestion of a typical granular backfill example with Mohr-Coulomb properties: gamma 19kN/m3, c' = 0, phi' = 30 deg, E=15,000kPa what would be a suggestion for a Hardening Soil model + Plaxis input properties to give a similar characteristic granular soil?

I think the formula for Eq (140) at 1:54 sec is incorrect. The numerator should be c*cos(fi)+sigma3 (not -sigma3)
