bekker_pressure — DRIVE roverslip op

• Data kinds: signal × scalar × any → signal

• Call: import fullseye as fs; fs.ledger.bekker_pressure(sinkage, width, soil) -> 'np.ndarray' (to call the implementation directly, import roverslip; roverslip.bekker_pressure(sinkage, width, soil) -> 'np.ndarray'; from the registry, opsdrive.get("bekker_pressure"))

Usage

> This operator's description has not been translated yet. The original text follows as it is.

Bekker の圧力–沈下 `p = (k_c / b + k_φ) zⁿ [kPa]。sinkage [m] はスカラーか配列(≥ 0)、width` = b [m]。

返りは `sinkage` と同じ形の配列(スカラーなら 0 次元)。z = 0 で 0、z について単調に増える。
