Hello everyone, I encountered some problems when I used LS-DYNA module in ANSYS WB to do drop simulation analysis. I obtained the stress-strain curve of EPE material through uniaxial compression test, and created EPE material in the engineering database to input the test data and used second-order Ogden constitutive to fit the material as shown in the figure. When I solve in the LS-DYNA module when the system reported an error, I do not know how to solve, hope to have the big guy advice, thank you (I found that the Ogden model I defined worked fine in "Static structal", but there were errors in LS-DYNA)

When I used the internal rubber1 material model in ANSYS, I found that I could perform normal calculations

I need some help,thanks

Hi

I suggest to post this in the LS-Dyna forum.

 

Thank you
