Hot embossing in ANSYS

Submitted by dhananjay1984 on

dear all,

 

Finally i found out the way to simulate PMMA embossing using Mooney Revlin constants at several tempature. Now i am trying to include Prony model and shift function with Hyperelastic model in ansys. I tried using static and transient analysis but it is not giving viscoelastic flow behaviour. If anyone done this kind of simulation in Ansys please help me. I am sending mooney revlin and prony model constants in ansys WB.

 To be included in command file..
