Hello everyone,
I'm currently doing some drilling simulations on Abaqus. My model is well working however my results are not so easy to analyze.
I work with Explicit solver, Dynamic simulation, 3D elements. I also use element deletation in my mesh and a failure criteria.
As you can see on the attachement, the curve is done of several peaks. Is it because Abaqus calculate layer by layer ? And so the thrust force is maximum just before each layer breaks.. Or is it because the software is not able to converge?
To give you an idea, the literature review shows it should be like that:
One more thing is about the time period on Abaqus. I don't really get what it is in reality. Is it the real duration of the experiment? Or is there a scale factor?
Thanks for your help which will give me main keys regarding my work.
Sincerely,
Loïc
