neohookean_cylinder_exact — DRIVE tacdome op

• Data kinds: signal → table

• Call: import fullseye as fs; fs.ledger.neohookean_cylinder_exact(d, mu: 'float' = 1.0, area: 'float' = 1.0) -> 'dict' (to call the implementation directly, import tacdome; tacdome.neohookean_cylinder_exact(d, mu: 'float' = 1.0, area: 'float' = 1.0) -> 'dict'; from the registry, opsdrive.get("neohookean_cylinder_exact"))

Usage

Exact solution for frictionless uniaxial compression of an incompressible neo-Hookean cylinder (a textbook continuum-mechanics result, independent of the model).

> The detailed description below is the original text — the summary and the headings are translated.

伸び λ = 1 − d、横は λ^{−1/2}(体積一定)。公称応力 P = μ(λ⁻² − λ)(圧縮を正)、Cauchy 応力 σ = μ(λ⁻¹ − λ²)、力 F = P·area、線形の力 3μ·d·area(E = 3μ)、kappa = F/線形、radius_ratio = λ^{−1/2}。Raises ValueError: d が [0, 1) の外、μ・area ≤ 0。
