Expand description

Nonlinear rockfill material model.

Models coarse granular fill with stress-dependent friction angle and stiffness (e.g., for earth/rock dams).

Fields§

§phi_base: f64

Base friction angle at reference stress [radians].

§delta_phi: f64

Friction angle reduction parameter delta_phi.

§sigma_ref: f64

Reference confining stress for phi reduction [Pa].

§modulus_number: f64

Modulus number K_mod (Janbu).

§modulus_exponent: f64

Modulus exponent n_mod (Janbu).

§p_atm: f64

Atmospheric pressure for normalization [Pa].

§e_max: f64

Maximum void ratio (loose state).

§e_min: f64

Minimum void ratio (dense state).
