Nanoscale Stress Distribution in Silica-Nanoparticle-Filled Rubber as Observed by Transmission Electron Microscopy: Implications for Tire Application

Nanoparticle-filled rubber under tensile deformation was observed in situ by transmission electron microscopy (TEM), and the spatial distributions of the local maximum and minimum principal strains (εmax and εmin) under tensile deformation were determined experimentally for the first time. The local εmax showed that deformation behavior depends heavily on the local structures and their spatial arrangements. Additionally, greatly deformed rubbery...
