Ive been pretty unsuccessful with a FEA analysis I want to do on ANSYS 14.0 with experimental data I recollected from the tension testing machine using UHMWPE at 50C.
I cant say I have a lot of experience with ANSYS, even less, on polymers. But as far as my research tells me I require a material model to create a strain energy density function. In ANSYS, only the Yeoh model could do a curve fitting with the uniaxial tensile stress-strain data I have. But I realize I am using it as a hyperelastic model, probably the reason why the results are so far-fetched. Digging deeper I think I will need to use the Hybrid Model in MCalibration and then insert it in ANSYS WB. Am I right? Or can I still do it using only ANSYS?
Is it proper and enough to use only tensile stress-strain experimental data?
Do I require time data in the tensile experimental data considering I want to do a structural analysis under a fixed load?
In advanced, thank you very much!
