A viscoelastic beam theory of polymer jets with application to rotary jet spinning

摘要: Abstract Complex deformation of a polymer jet appears in many manufacturing processes, such as 3D printing, electrospinning, blow spinning, and rotary spinning. In these applications, melt or solution is first extruded through an orifice forms jet. The then dynamically deformed until the solidifies. final product strongly affected by And viscoelasticity polymer. Here we develop beam theory to incorporate both nonlinear bending/twisting stiffness As demonstration, study formation fiber under strong centrifugal force, process known
