bearing.phi_from_toe_bearing_grid()
Friction angle from toe bearing by interpolation on a fixed grid.
Usage
bearing.phi_from_toe_bearing_grid(
q_needed,
sigma_v,
options,
)Parameters
q_needed: float or array_like-
Required unit toe resistance, ksf.
sigma_v: float or array_like-
Vertical effective stress at the toe, ksf.
options: ModelOptions- Supplies the friction angle bounds and rigidity parameters.
Returns
float or ndarray- Friction angle, deg, clamped to the bounds. Faster than phi_from_toe_bearing when evaluated many times.
