Dear Gopal,
Please find the attached hm file.
Thanks

Hi,
I was going through the model and following issues are noticed.
1) Penetration and intersection needs to be cleared.
2) Quality of mesh needs to be reviewed . Warpage <15, skew<40, jacobian>0.6, min. length now is 2.15 can be increased for better time step etc.
Is the material property entered is test data ?
Also I think you have not taken the output for the reaction force Vs displacement. This can be done by making the RBODY for both upper and lower actuators and then requesting output blocks for it , so that you can compare the same with experimental data.
Also model washers at the mounting locations as maintained in physical testing.
Have you also tried with imposed displacement/velocity as load instead of force?
Dear Gopal,
In this journal they co-related the results for H1H2 test
Hi Ram,
Even though this kind of analysis seems to be a quasi static problem it involves strong contacts and chances of local buckling. And I think It's quite difficult to converge in implicit.
But give a try.
Meanwhile please see a research paper in this link where a similar analysis was done: https://edupediapublications.org/journals/index.php/IJR/article/download/3096/2973
Hi,
Can you share the .hm or .rad files for this .(version 13)?
