Transient Behavior of a Polymer Fill Material with Time Dependent Viscoelastic Properties
In an effort to simplify the implementation of viscoelastic material models into ANSYS, an ANSYS User-Programmable Feature (UsrFictive) has been modified to allow a more practical definition of viscoelastic material parameters. Standard ANSYS input of material data may be based upon temperature. Currently, ANSYS material data may not be a function of any other parameter. Many polymers used in industry are initially liquid and must be “cured” in a manufacturing process. This fact means that the properties will change over time. This application demonstrates one method of implementing a curing process simulation for a viscoelastic polymer.
