How to get Hysteresis graph for solid base isolator using ABAQUS SIMULIA

[syura_]

Hi and good morning to all, I have a problem regarding the hysteresis graph where I get either linear or not proper results of hysteresis. I already try to adjust the material property, load and step but non-work. May anyone help me check where actually I was wrong and I can adjust? Here I attached the reference paper and the abaqus cae (where currently i edit at C SOLID BASE-edit dr-Copy. Thank you so much

What is the title of this article ? The information provided in this excerpt is not sufficient to build Abaqus model.

The name of titile is stiffness and Damping Comparison of Solid and Hollow Seismic Isolator and Non-Seismic Design Rubber Bearing for Bridges. I also attach the reference paper. Thank you

I would refine the mesh but hyperelasticity seems to be crucial here. Make sure that you defined it properly, based on the data from the article. Maybe try with different material models - you can perform a material evaluation in Abaqus to check which hyperelastic model fits the test data best and generate coefficients for it. Also, the article omits some important information (like interfaces between layers) so it might be difficult to get good agreement with it.
