From: Modeling the formation of Sedan Crater using the FLAG and HOSS codes

HOSS Material model curves. Left: Yield surface for the 3-invariant strength model. The strength plotted in here corresponds to \(\sqrt{3J_2}\), where \(J_2\) is the second invariant of the deviatoric stress tensor. Right: EOS curves for alluvium, featuring the elastic, pore crushing, and fully crushed portions of the model. In this graph \(\mu =\rho /\rho _0-1\) where \(\rho\) and \(\rho _0\) are the current and the initial density of the material respectively.
