Bearing & shear-out stress API

Computes bearing (hole crushing) stress P/(d·t) and shear-out (tear-out) stress P/(2·e·t) for a pin in a plate, with factors of safety against allowables. Answers 'Will the bolt hole crush or tear out?', 'Is my edge distance enough?'.

Example request

{

  "boltDiameterMm": 10,
  "plateThicknessMm": 8,
  "edgeDistanceMm": 20,
  "allowableBearingMpa": 300,

}

Example response

{
  "bearingStressMpa": 150,
  "bearingAreaMm2": 80,
  "formula": "σbr = P/(d·t); τ_shearout = P/(2·e·t)",
  "interpretation": "Bearing crushes the hole; shear-out tears the material to the free edge — both must clear allowables.",
  "shearOutStressMpa": 37.5,
  "shearOutAreaMm2": 320,
