mindlin_model — DRIVE tacslip op

• Data kinds: table × matrix × matrix × table × scalar × scalar → table

• Call: import fullseye as fs; fs.ledger.mindlin_model(hz: 'dict', X, Y, kern: 'dict', G: 'float', nu: 'float') -> 'dict' (to call the implementation directly, import tacslip; tacslip.mindlin_model(hz: 'dict', X, Y, kern: 'dict', G: 'float', nu: 'float') -> 'dict'; from the registry, opsdrive.get("mindlin_model"))

Usage

Inverse model that produces the Mindlin displacement field for any c/a via similarity laws (only 1 convolution).

Hertz 形の接線トラクション(半径 R、頂点 q0)の表面変位は u = q0·R·ĝ(x/R)(線形弾性 + 無次元化)。q′(半径 a、頂点 μp0)と q″(半径 c、頂点 μp0·c/a)の差だから、g(x) = 頂点 1 Pa・半径 a の場として u(x; c) = μp0·[g(x) − (c/a)²·g(x·a/c)]。g は Cerruti 核で格子上に作り、x·a/c が格子の外に出る点は点荷重の漸近形(総力 (2/3)πa²·1 Pa)で補う。順方向の畳み込みとの差は核で 0.05 %、環で 0.13 %。返り gx・gy(n, n)、Qunit、n・pitch・c0(格子中心 [px])、hz・G・nu。c/a の格子を線形補間する模型は場が c に非線形なので c/a を 0.01 ずらした(捨てた)。Raises ValueError: 形の不一致、G ≤ 0。
