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...

Hi everybody, I'm currently running some simulations on Abaqus, and I need to use CFRP material in my simulation. I've gathered all the data, and tried to use them in Abaqus. The thing is the Hashin Damage Model doesn't work with 3D elements (which ones I use in my simulation) and only works...

Yeah I think so. Actually some chips are created during the simulation, but they don't look real, and for example they don't exit all along the flutes but by the other side of the hole. The workpiece is made of titanium, and the material data I chose are quite good I think. Later I will add a...

Thanks so so much ofr your detailed explanations. You gave me the way to succeed. Thanks so much, no let's optimize the mesh and simulate chips... By the way, do you have an idea regarding the chip formation? I still have to investigate that, but for now I've not found a proper way to do...

Hi, Thanks very much, I try to figure it out with your picture and get in touch with you,

Hi, As you told me, I took the time to investigate the documentation of Abaqus, and even if at the beginning I thought it was not helpful, it finally was!! I finally started again the design of my simulation on my own on Abaqus, and I think I understand everything more deeply. The thing is...

Yeah I agree for the tie. However I don't understand for the regular contact sorry. By the way I search on the internet for my problem and find something which explains that it was due to the necessary to give a mass and an inerty moment.. But still not work. If someone has an idea, I'm still...

Thanks you for your method, it is different from mine but seems to give a good result as well ;)

Finally, with tenacity I've been successful. Admins, you can close the thread. Thks

If you mean this one... (cf attachement) http://files.engineering.com/getfile.aspx?folder=6a12c034-b327-4603-811e-92da9885ab14&file=Sans_titre-10.jpg

Thank you. OKay, but the two things are different.. Let me know if I'm wrong, but the Tie constraint I used is to constrain the cutting edges, while the friction coefficient is to manage the contact between the tool and the workpiece... One doesn't rule out the other, isn't it ? Thks

Thanks for your answer. By angular what do you mean? Which angle are you talking about? Thanks very much

Hello everyone, I'm currently designing a drill bit on Catia v5, but I don't manage to complete the last step I want to do, which is creating the split point (135°, 4 facets). For the angle it is okay, but I don't manage to create the 4 facets. I'd like to do something like that: And for now...

Hi everybody, I'm in my first year of master's degree in mechanics and materials, and currently doing an internship for which I need to perform some simulations on Abaqus. I work on a drilling process: carbide is used for the drill bit, and titanium for the workpiece. I created the model on...
