Poroelastic parameters

effstress(nu, nuu, B)

poroelastic_stress_coefficient(nu, nuu, B)

biot_willis_effstress(K, Ks)

biot_compressibility(nu, nuu, B, mu = 1)

darcy_conductivity(nu, nuu, B, mu = 1, diffusiv = 1)

lame_first(nu, mu = 1)

`nu`	numeric; the drained Poisson's ratio [0,0.5]
`nuu`	numeric; the undrained Poisson's ratio [0,0.5] (`nu` < `nuu`)
`B`	numeric; Skempton's coefficient [0,1]
`K`	numeric; the bulk modulus
`Ks`	numeric; the constituent bulk modulus (e.g., one from an unjacketed lab test)
`mu`	numeric; the isotropic elastic shear modulus (keep at unity for 'normalized')
`diffusiv`	numeric; the isotropic hydraulic diffusivity (keep at unity for 'normalized')
