I am recently trying to run a SINGLE ELEMENT simulation of PTFE with Abaqus and I am facing a problem. If you can help me, I would be really glad.
I have Uniaxial tension experiment data, and I have put this into Test Data Editor (as uniaxial test data). While putting it, I have made some changes in the data since it was saying:
Error in job Job-1: THE NOMINAL STRAINS UNDER THE *UNIAXIAL TEST DATA OPTION MUST BE ARRANGED IN ASCENDING ORDER
Here is my question,
I am running the simulation:
Hyperelastic Material with Marlow strain energy potential ( I think I do not have any other choice since I only have one set of data)
I extract True Stress vs. True Strain data ( Centroid, all elements which is one).
When I compare Stress vs Strain diagrams of experiment and simulation, there is a big difference. I am trying to get the same behavior from experiment.
Could you please suggest me someway or a model to get the same curves?
