Nanofiller Load Transfer — Shear-Lag Model in Polymer Nanocomposites

Interactive shear-lag simulation of how stress transfers from a strained polymer matrix into an embedded nanofiller (nanotube, nanoplatelet or nanoclay platelet). Tune aspect ratio, volume fraction, filler stiffness and applied strain and watch the axial stress build up along the filler and the interfacial shear stress peak at its ends.

Reinforcing a polymer with nanoscale fillers works only because stress can cross the polymer–filler interface. This simulator renders the Cox/Kelly–Tyson shear-lag model in real 3D: a hero nanofiller sits inside a strained polymer matrix, colored along its length by the axial stress it actually carries, while the interfacial shear stress that put it there peaks visibly at its two tips. Sliders for aspect ratio, filler volume fraction, applied strain, filler stiffness (carbon nanotube, graphene, nanoclay or glass fiber for scale) and alignment update the stress profile and a set of live readouts — composite modulus, shear-lag length efficiency, peak interfacial shear stress and the critical-length ratio — showing exactly why aspect ratio is the property nanofillers exploit that microscale fibers cannot.
