*LSDYNA ADHESIVE BOND ANALYSIS*
===============================

Single-joint adhesive bond analysis from LS-DYNA secforc output. Computes lap shear, peel, quadratic-interaction, and Benzeggagh-Kenane mixed-mode FOS time-histories for a bonded joint. Built-in database of structural adhesives (Henkel Teroson EP 5055 / SB 2705 / MS 9320 / PU 9225, Loctite EA 9462, Macroplast UK 8202, plus generic epoxy / PU / MS-polymer / cyanoacrylate / methacrylate) with substrate-pair derating (steel-steel, steel-alu, alu-alu, steel-CFRP, glass-glass, plastic-plastic) and temperature derating per resin type. Standards supported: ASTM D1002 / D3163 / D3433 / D5573 / D2095 / D6862 / D903, ISO 4587 / 11003-2 / 11339 / 9664 / 13003, VDA 4901, GMW 14179, SAE J1523 / J1532. Returns per-section FOS curves + min summary suitable for downstream charting.
