摘要: Processing conditions play an important role in the structure-property relationship of semicrystaltine polymers. The temperature and deformation rate history can affect growth nucleation crystallization for a semicrystalline polymer. flout heat transfer during processing be strongly coupled to equations material kinetics In this study, effect coupling on polymer is studied driven cavity under nonisothermal conditions. transient analysis flow polymeric melt modeled as power law fluid with dependent viscosity. Results are shown evolution crystallinity strain time various velocities moving plate aspect ratios polyethylene, fast crystallizing importance effects shear-induced crystallization, flow, shown.
