Tensile pull on adhesive polymer chains
Work by Scott Sides, Gary Grest, and Mark Stevens, all at Sandia, on adhesive properties of polymers.
The simulations are of melts of 500- and 1000-mer bead-spring chains. The systems range from 100K to 500K total monomers and are run for 10-20 million timesteps. In these snapshots of models with different parameters, the blue chains are the melt, red are tethered and unbroken chains, green are tethered and broken.
