• Molecular Orientation in Large-Amplitude Oscillatory Shear (LAOS) of Complex Fluids 

      Gilbert, Peter
      Polymer rheological properties are important to modern manufacturing, and though polymers have been studied for decades, we still do not fully understand how polymers flow. Subjecting a polymeric liquid to oscillatory shear ...
    • Polymer Process Partitioning: Extruding Plastic Pipe 

      Saengow, Chaimongkol (2016-09-14)
      When plastic pipe is solidified, it proceeds through a long cooling chamber. Inside this chamber, inside the hollow extrudate, the plastic is molten, and this inner surface solidifies last. Sag, the flow due to the ...
    • Slip Heating in Polymer Processing 

      Gilbert, Peter (2014-12-04)
      When one body slips on another, heat is generated at the slipping interface. We call this phenomenon slip heating and apply slip heating theory to cohesive and adhesive slip in extrusion dies. Adhesive slip, which is linked ...
