Abaqus, fatigue test on a dental implant

Abaqus, fatigue test on a dental implant

Abaqus, fatigue test on a dental implant

(OP)
Hello,

I have a job I've been given, I'm a student, in an internship, and I just started using Abaqus.

So I have to simulate a fatigue test on a dental implant, shown on the following links :

- The implant is recessed on his thread (the part that's being screwed, I'm sorry I'm french so I'm not quite sure of the technical terms, if you find something sound weird, please tell me)
- On top of the implant, there's a false stump, on which is place, as a surface to surface contact, a very very thin plate, dimensionally stable, on which is applied a ponctual force. This plate being there only for the ponctual force to be spread as a pressure on the false stump.
- The force is applied with an angle of attack of 30°, and is supposed to oscillate between 15 N and 150 N and to performe a full cycle in 0.1 second (meaning go from 15 N to 150 N, and back to 15 N all in 0.1 second).
- The study is performed in a way that 5 millions cycles are done, and I'm supposed to determine what is the maximum force I can go to before the implant breaks (I start by doing 15 N to 150 N tests and can go down if it breaks)
- The goal is that after the 5 millions cycles, the implant is not broken.

So i theory, the concept is rather simple.

Except that I don't really know (actually have no idea) how to simulate that. I've been using Abaqus for only 3 weeks now, and what's more, fatigue is a subject we treat only next year...

So I have to know how to obtain a simulation of the strains, stresses, displacements, weaknesses, damages, and eventual fractures (implying a force too strong) that would imply such a fatigue test.

Anybody can help ? It's really important to me, I've been searching on the internet, and in Abaqus but it's been a week that I'm working on this now, and still have no idea how to it...

I watched this tutorial :

But unfortunately, doing it (while adapting it to my problem), didn't work...


Thanks a lot to anyone who help me.

Have a nice day.


Benjamin.
