Simulation of bridge die extrusion using the finite element method [PDF]

open access: yes, 2001
This communication reviews previous work on the extrusion of hollow shapes and uses a three-dimensional (FEM) solution to predict load-required, temperature of the extrudate and material flow during the process.

Preparation of Biodegradable Materials by Reactive Extrusion [PDF]

open access: yesMaterials Science Forum, 2008
This work aimed to prepare biodegradable polymeric materials based on blends of a synthetic high density polyethylene (HDPE) and biodegradable polymers such as polylactic acid (PCL) and poly(caprolactone) (PLA), in a co-rotating twin-screw extruder. A polyethylene modified with maleic anhydride was used as compatibiliser.

Simulation of gelled propellant doughs isothermal flow through extrusion dies using finite difference method [PDF]

open access: yes, 2017
During the ram extrusion of gelled propellants, the possible flow instabilities can affect the extruded propellant quality. The numerical modelling helps to enhance the geometry of extrusion die, by minimizing the product distortion caused by material ...

Mesoscale Modeling of Extrusion and Solidification During Material Extrusion Additive Manufacturing

open access: yesRecent Progress in Materials, 2023
In this work, we apply a multiphysics approach to fused deposition modeling to simulate extrusion and solidification. Restricting the work to a single line scan, we focus on the application of polylactic acid. In addition to heat, momentum and mass transfer, the solid/liquid/vapor interface is simulated using a front-tracking, level-set method.
