Polymers Designed for Protection (IMAGE) U.S. Army Research Laboratory Caption The new AIREBO-M Potentials were validated against a pressure-volume isotherm at T=533K for polyethylene crystals. The AIREBO-M potentials showed nearly perfect agreement with REAXFF calculations and experimental data. However the AIREBO-M potentials were much more computationally efficient than REAXFF calculations, and allowed upscaling of calculations to perform much larger simulations.
