hi all,
I have a gear pair model consisting of solid elements, which is used to simulate wear behaviour.
we have followed all the steps as mentioned by the following pdf : simulation-of-wear-processes-in-ls-dyna.pdf
INTFOR is showing the Wear slide & Depth Fringe , but the issue is that inspite of adding the following cards , *INITIAL_CONTACT_WEAR data is not been written in the dynain file.
Cards used :
*CONTACT_AUTOMATIC_SURFACE_TO_SURFACE_ID (SPR/MPR are set to 2)
*CONTACT_ADD_WEAR (above contact cid is added with p1,p2,p3)
*DATABASE_EXTENT_INTFOR (nwear=2)
*INTERFACE_SPRINGBACK_LSDYNA (PSID is mentioned).....
please let me know how to get the dynain with wear data written....
thanks in advance.
Hey @geardyn-1,
Sorry I've been afk for a bit. I know everyone has been appreciative of your replies.
Anyways, curious if you solved this issue or not. Sounds like the issue might be an intermediate like the version of dyna you were using or your pre-post version.
Anytime I use dynain files I'm importing them in Primer so I'm sure there's some jank with LS-Prepost.
Thanks for the reply . . . Appreciate it
I was not able to resolve the issue with the version we had . Also the wear analysis methodology is extensively built for Metal forming process/industry . if we apply this method for any other application , we wont get proper results.
Also , the methodology involves postprocessing based on the data written in Dynain file. So even the latest pre-post was not helpful to this particular application.
If ok, please drop me an email to geardyn.1@gmail.com , i shall send this sample file for your reference
@geardyn-1 yeah, I'm not sure how well Dyna can simulate something like wear. Have you read this?
It might be something more suited for Abaqus?
