hertz_cylinder — DRIVE `tacsim` op

• Data kinds: scalar × scalar × scalar → table

• Call: import fullseye as fs; fs.ledger.hertz_cylinder(F_per_L: 'float', R: 'float', Estar: 'float') -> 'dict' (to call the implementation directly, import tacsim; tacsim.hertz_cylinder(F_per_L: 'float', R: 'float', Estar: 'float') -> 'dict'; from the registry, opsdrive.get("hertz_cylinder"))

Usage

Line contact of a cylinder (radius R) pressed onto an elastic half-space with line load F/L (Johnson 1985 §4.2): contact half-width b = √(4(F/L)R/(πE*)), p0 = 2(F/L)/(πb).

返り: b、p0、pm = (F/L)/(2b) = (π/4)p0、入力。2-D の押し込み δ は対数的で参照点に依存するため返さない。Raises ValueError: ≤ 0。

• Sample-data catalog (download URLs / licences) — 2-D uses skimage.data (BSD/public domain) plus synthetic images; 3-D lists download URLs for real data sources (Stanford, PDS, …).

• Operator provenance and references — the sources of the research/methods this op family came from.

• The canonical algorithm (author, year) and its uses are named in the family usage guide above.
