Hi,

Im writing on this forum because Im a bit at a lost with an analysis conducted with ANSYS workbench.

Ive got creep response data and springback data: I used a test bench consisting of a constant weight pulling laterally a polypropylene flat bar (somewhat in the manner of a cantilever beam but pulled honrizontally)

SEE PICTURE in attachment

For the creep test: The heat gun warms the flat bar while the force is pulling on it: the magnitude of the angular deformation is measured as a function of time.

For the springback test: The heat from the heat gun and the force are both removed and the springback is measured as a function of time.

Ive developped a creep equation for the creep test that also figures in the ATTACHMENT.

With matlab, Ive fitted the equation and found the right parameters to fit my data.

I am now trying to model this experiment in ANSYS workbench. Ive read a bunch on the subject but Im having a hard time finding where to start and what should be included in my analysis.

From what I understand, I need to make a static structural analysis with the right temperature profile. That I can do. But so far, my analysis is carried out only in the elastic domain and this wont work since a permanent deformation remains in the flat bar, after the springback.

I know I must include PLASTICITY and VISCOELASTICITY in my material properties (like MISO and prony). But workbench asks for stress VS strain data and shear modulus VS time data. All I have is series of data of angular deformation (in rad) as a function of time (seconds).

How can I use my results in Workbench? Can I include my creep response equation in Workbench?

How should I make an FEA analysis of this experiment using Ansys Workbench? Im a bit familiar with command snippets in mechanical but I know next to nothing of mechanical APDL (Ansys classic)

Please help me, my director knows nothing in ANSYS and nobody at my university either
