Hello Zhao,

If your research institution has commercial Ansys licenses, you can file a support case.

You can reduce sliding energy by trying the methods I explained before (SOFT=2, SBOPT=3, DEPTH=35), reduce TSSFAC, and reduce BSORT. 

You will find more information on contact energy here:

Contact Energy — Welcome to the LS-DYNA support site

And more information about contacts in general here:

Intro-to-Contacts.pdf (oasys-software.com)

I like the above seminar from our channel partner Arup.

If you increase the d3plot output frequency, you might be able to see the contact problem. I suspect node penetrations that is not detected leading the larger forces on the blank. 

 

Let me know how it goes.

 

Reno.
