LinearElastic

Define a Linear Elastic material.

Parameters

name : str: String naming the material.
color : Color: Material appearance. color= rgb(0,56,122)
drainage : str: Material drainage type. drainage = 'drained_undrained', 'always_drained', 'non_porous'
cavitation_cutoff : str: cavitation_cutoff = 'no' or 'yes'
pcav : float: Cavitation pressure, in kPa.
E : float: Young's Modulus, in MPa.
nu : float: Poisson's ratio.
gamma_dry : float: Dry unit weight in kN/m^3.
gamma_sat : float: Saturated unit weight in kN/m^3.
K0 : float: Earth pressure coefficient at rest.
hydraulic_conductivity_option : str: hydraulic_conductivity_option = 'isotropic' or 'anisotropic'
K : float: Hydraulic conductivity, in m/day.
Kx : float: Hydraulic conductivity in x, in m/day.
Ky : float: Hydraulic conductivity in y, in m/day.
Kz : float: Hydraulic conductivity in z, in m/day.
hydraulic_model : str: hydraulic_model = 'basic' or 'van_genuchten'
e : float: Void ratio.
alpha : float: Model parameter related to the air entry pressure.
n : float: Model parameter related to the rate at which water is extracted from the soil once the air entry pressure has been exceeded.
Sr : float: Residual degree of saturation (may be slightly greater than 0).
Ss : float: Fraction of water filled pores at full saturation (may be slightly less than 1).
tension_cutoff : boolean: Apply tension cutoff. tension_cutoff = 'yes' or 'no'
sigma_t : float: Tensile cutoff stress, in kPa.
