STENT expansion inside artery 1

[drkc01]

Good morning everyone

I am a student working in determination of fatigue in stents inside coronary artery using Abaqus
Things I have done - modelling of artery and stent, Using ART plugin, expansion and crimping of stent

Now I am working to do the expansion inside artery, working in contact using ART plugin. I am stuck here. If anyone is interested i can upload my inp files and figures. I need some suggestions whether on to create a new subroutine for the contact or ART plugin would just help me do it. I was just trying with the subroutine provided by the plugin but not reaching anywhere. Anyone with experience on that plugin please reply to this thread

Thanks

Can't you just deactivate the interaction between the ART and the stent in one step and activate the interaction between the stent and the artery in another step?

Are you new to this forum? If so, please read these FAQ:

I was going to do that but I have run into other problems.

I have subroutine (Uhyper)for arterial layers and rsurfu for ART plugin. A quick goggle search had me combining those two subroutines in one file just copy and paste, since they are not related. I did that and i have the error now 'problem during compilation'. so something is not right. Now I know those two work just fine when i run them separately so what am i missing here.
