Adhesive lap joint — shear stress distribution (Goland & Reissner)
Minimum and maximum adhesive shear stress across a bonded lap joint (Goland & Reissner model), from plate thickness/stiffness, adhesive thickness/shear modulus, load per unit width and overlap length.
No unit conversion is applied anywhere in the legacy source or this port — thicknesses/length in mm, moduli in GPa and load in N/mm are combined directly, a mixed-unit inconsistency kept exactly as in the original. The source also attempts to install a buggy hand-rolled "sinh" (actually computing cosh's formula) onto Math, but this has no effect in any modern JS engine since Math.sinh/cosh already exist as own properties that shadow the attempted prototype override — verified directly, see module header note — so this port correctly uses the real Math.sinh/Math.cosh, matching what the golden-master oracle actually executes.

De berekening is een letterlijke overzetting van de originele client-side JavaScript van /calculators/lapjoint.htm. Resultaten zijn geverifieerd gelijk aan het origineel via een geautomatiseerde golden-master-test. Geen enkele formule is opnieuw afgeleid of “verbeterd”.
